  • 00:00:00 The importance of using seismic isolation in important buildings is discussed in this virtual seminar. Examples of such buildings include schools, hospitals, and prisons. Although the process of converting these buildings to use seismic isolation can be difficult, it is important for the development and happiness of people.
  • 00:05:00 In this virtual seminar, engineer Luis Espinola discusses the importance of using seismic isolation in essential buildings. He notes that working together we'll discuss his experience, which passed him in January. "As love thinks, so does anger. Anger loves to do battle." -Plato Today's topic is important, so let's get started. Luis Espinola, engineer, is here to talk about the importance of using seismic isolation in essential buildings. He notes that working together we'll discuss his experience, which passed him in January. Segment 1: Introducing the Topic In this segment, Jorge Lacruz, engineer, discusses the importance of using seismic isolation in essential buildings. He emphasizes the importance of having a minimum distance of one meter and one and a half meters, and recommends that hands and arms be recorded at a frequency corresponding to the risk. Segment 2: The Benefits of Seismic Isolation In this segment, Luis Espinola discusses the benefits of using seismic isolation in essential buildings. He points out that seismic isolation not only protects people and property, but also helps businesses grow and improve their efficiency. Segment 3: The Importance of Training In this segment
  • 00:10:00 The importance of using seismic isolation in important buildings was highlighted in this virtual seminar. Standardization for success was discussed, and Peru's experience in engineering and technical procedures for building the National Institute of Diseases of the Blood was presented. International experiences in using vibration damping and seismic retrofitting were also discussed. The engineer, Luis Espínola, has more than 20 years of experience in designing hospitals, and spoke about the new Hospital of Puno. He also addressed common questions about seismic isolation and damping devices. In the next segment, Mr. Espínola will present the seminar's main topic: introductory basics of seismic design.
  • 00:15:00 This video discusses the importance of using seismic isolation in essential buildings. 15 years after a major earthquake struck, this bridge, which is an essential bridge, survived easily despite that strong earthquake that has affected other bridges that were 10 kilometers away. Whereas this bridge, which is a bridge of vital importance because it carries a 15-inch water pipe, saved the different district of San Vicente from the bottom of the San Vicente reservoir, it is also the access route if the district did not have to make a full circle trip. This tank was designed to prevent damage from earthquakes or a 20-point damage, and a crack can develop due to this. Gas exiting the tank after it is filled with gas can provide oxygen and another thing to consider is that Melchorita is a very soft land and the isolation units that were installed are isolation units of automotive friction. Saturday was the whole installation process for this type of isolation unit because it has a great displacement and is a bad land. The purpose of this tank is that it should not be stopped in its tracks, and it should not experience damage. Two years as seen in this video could be avoided if seismic isolation was only used to protect hospitals only, but this is not the case. All places where large numbers of
  • 00:20:00 The importance of earthquake isolation in essential buildings is discussed in this virtual seminar. A standard of construction that guarantees a perfect function in the event of a severe earthquake is not currently in use, but it has been proven to be effective. If you don't have an earthquake isolation standard for building materials, you also won't have one for your structural elastomers. Any good Emiliano-type elastomer will have a 0 percent capacity at the upper and lower limits in the middle. I am talking about the standard of design and construction of all the grades I have known of, which is to minimize the impact of the earthquake on structural elements. Earthquake isolation is a design method, not a performance criterion. Using international codes such as the R-value, which we have seen in previous videos, doesn't give us minimum standards. We need to design buildings for use in an earthquake environment that comply with the S-code. Structural elements must be limited in their damage and acceleration. For hospitals to be able to function during and after a major earthquake, they need to use an S-code design. The current design philosophy, which is based on Newton's first and second laws of motion, is no longer sufficient. We need to use international standards such as the J
  • 00:25:00 In this seminar, it is shown that the use of seismic isolation in essential buildings is important in order to minimize damage in the event of a seismic event. Exciting demonstrations are given of how seismic isolation can be used to protect against seismic damage, and how it can be used to limit the impact of seismic waves on surrounding structures. Two types of seismic isolation are discussed- elastomeric and metal-reinforced plastic. The importance of validating the isolation system using dynamic tests is also highlighted. In terms of design, seismic isolation is important to consider when designing structures with competing users and sensitive content. The use of elastomeric isolation is shown to be a viable option when designing structures with a high seismic risk.
  • 00:30:00 This video discusses the importance of using seismic isolation in essential buildings. It explains that the least required protection in dynamic tests is required by the S-76 standard, and that the 0-31 standard also requires this. You have the option to choose between dynamic or static tests. If you design an essential building, you should use dynamic tests instead of the static tests. You should also consider the quality of the seismic isolation when certifying the installation. This type of isolation has a certification for that very purpose. The force used to determine the fire risk sees the video go on to show a dynamic test of a staircase. The second staircase is shown when the test is done in seconds, but because the test is not static, it is not an estatic test. Each type of seismic isolation for a building must be tested in a very clear way for each model. The manufacturers must specify the lower and upper limits of the force and displacement applied in these tests. We will now see how this type of isolation works in freedom. Fidel is at the top, and we see the isolated structure at the top. We see the structure at the bottom, which is not isolated, and below that we see the unisolated structure. We then see the structure in between being isolated when the movement
  • 00:35:00 The importance of earthquake isolation in key building structures was discussed in a virtual seminar. Engineer Abel said that, unfortunately, any time is bad because President 7 believes that we are waiting for a great earthquake, for example, here at the Hospital of Manta. Damage done to architectural elements and structure in the Hospital of Portoviejo and the Column in Córdoba, Argentina were seen as examples of the importance of seismic protection in hospitals. The Peruvian hospital infrastructure does not have such protection in place, and as a result, many hospitals have been demolished after earthquakes. The seminar discussed the importance of seismic protection in hospitals in terms of protecting investments. For example, the Hospital of Chone in Ecuador was designed with seismic isolation in mind, and the hospital in Lechones, which was still under construction, had its walls collapse due to the quake. The new hospital, designed to have a mixed mode of operation, is being built with public funds. A hospital in Carpas, after experiencing a strong earthquake, was not able to serve all of its patients due to the lack of seismic protection. In order to design hospitals that will be able to withstand strong earthquakes, we need to know the seismic behavior of the regions in which they
  • 00:40:00 The importance of using seismic isolation in important buildings was highlighted in thisvirtual seminar. One characteristic of seismic isolation is that it can be seen clearly on the plans shown. In this project, an important structural issue was not easily visible until after an architectural design was created. However, the main point is that the structural integrity of the building was improved. Various details of the project were shown, including the use of seismic isolation in the stairs and cistern.
  • 00:45:00 The video discusses the importance of using seismic isolation in important buildings, and shows a variety of examples. One hospital, built in just six months, achieved compliance with safety guidelines thanks to its well-designed area isolation. The video also features a discussion of another hospital, built in just four months, that uses damage assessment to achieve compliance with safety guidelines.
  • 00:50:00 This video discusses the importance of using seismic isolation in important buildings. It shows how a pixel-based project was created using finite elements, and how important it is to consider all the details when designing a building. The hospital shown was designed using an elastic structure, which has allowed it to withstand earthquakes better than traditional hospitals. The video also discusses the design of the main entrance and other details of the hospital. In five months, the entire project was completed, an impressive feat given the many specialist areas involved. The time-record for this type of project was five months, a very short time for such a complex undertaking.
  • 00:55:00 In this video, a doctor explains the importance of using seismic isolation in important buildings, and shows how it can help protect people from earthquakes. The video also features a businessman who was in a building that experienced an earthquake and was amazed at how the building was moving smoothly.

This virtual seminar discussed the importance of using seismic isolation in important buildings. The speaker provided information on how to obtain seismic certification and on upcoming courses related to structural design.

  • 01:00:00 In Tokyo, seven people have died, but strange things are happening. Cracks in the ground are opening and closing, and in a process called "licuefacción," seismic shocks cause water from the ground to flood buildings. The earthquake registers 9 degrees on the Richter scale and has a force 600 million times greater than the atomic bomb dropped on Hiroshima. This energy would be enough to power the United States for 100 years. All of it exploded outward from a point in five minutes this earthquake is one of the five largest earthquakes in history. It's so powerful that it tilts the world 25 cm off its axis and shortens our days by almost 2 million seconds. The doctor briefly discusses her concerns about the earthquake of 9 degrees on the Richter scale, which was reported as having a depth of 34 kilometers. She is not able to stay upright in her building, which was isolated from the rest of the city. We don't know how badly the building was damaged, and we don't know if there were any greater damages done, but she is still very concerned. In the future, we will need to make a decision about how to deal with buildings that are not performing well in terms of seismic isolation. What we need to do
  • 01:05:00 This video discusses the importance of seismic isolation in essential buildings. The normal curve of a building's capacity is typically made based on the existing buildings in the area. If we were to evaluate an existing building and look at its capacity curve, the earthquake information tells us what the maximum and minimum points are. The point of performance can be located as seen in this example, which is a simple example of an immediate concern composed of safety of life, moderate damage. In terms of pre-collapse, it is already prior to the collapse of the total collapse, which is critical for this example. The last design is here at 85 meters with a cutting force of 2,407. It is well-done, but at the maximum sign, we are already in problems. Damage is severe and damage to the structure is severe, which is what cannot be in an essential building. A new Ecuadorian hospital, for example, experienced severe damage. Analysis of the example shows that the building's isolation devices are able to meet performance objectives, but the building's maximum probable Earthquake Ground Motion (EGM) would not be able to penetrate it. It is very high and that is something that should not be allowed. We'll go to the conclusions and what we've learned is
  • 01:10:00 The importance of using seismic isolation in critical buildings was discussed in this virtual seminar. The structure was updated to reflect the increased damage caused by a 30% increase in force. Traditionally, it is not recommended to use isolation barriers, and teaching this method by traditional methods with embedded devices is recommended. If you have a design criterion of achieving a damage greater than 30%, you should use the design method that was created in the 1970s. If you have a design criterion of using structural design for usefulness, you can choose the use method that was developed in the 1970s. Engineers need to think about the present and not just believe me when they offer a less expensive seismic isolation system, because that is not always going to be the case. In order to properly evaluate the system, the engineer must first understand the engineering design criteria. Next, they will ask a question from the public. Guillermo, please begin. Guillermo asks why seismic isolation is required in Peru, and the engineer responds that it is mandatory for the sake of safety. The purpose of the system is declared, but the question is asked about whether or not using the system with that design can achieve the objective of reducing damage by 2%. The engineer confirms that it can, and then asks
  • 01:15:00 The video discusses the importance of using seismic isolation in vital buildings, and how it is important for architects to take into account international standards when designing buildings. It also discusses a second standard, the Eurocode, which is less recommended because it does not require use of safety coefficients.
  • 01:20:00 The importance of seismic isolation in essential buildings was discussed in a virtual seminar. The designer or more or less that which will not be Ecuador then we have theConscious of safety then I prefer to go to a standard of a country that is inside the circle of fire to have a little more security because we who design we have a civil responsibility what we do then we have to take care what we are doing because if not all of us are going to pay we're not true I'm not what you have paid for an editor won't reach to pay the lawyer who defines and now that it is under control everyone of us designers and architects thank you engineer, thank you for this here is another question from google Good afternoon very good poster presentation life useful device seismic isolator exists a technical procedure for its maintenance of operation Hello I recommend for something that is common to all the elements you can put a construction in this case, seismic isolators and juices part of the work must have the same life-span as the building which is the life-span of
  • 01:25:00 The importance of using seismic isolation in important buildings was discussed in a virtual seminar. There are several problems because the standard says buildings must be isolated correctly, but there is a zone within buildings called a "complementary area." Sometimes architects or engineers design complementary areas, and then install a water tank with an electric generator there. This can create a lot of noise and vibration. One question was asked: is it necessary to isolate structures with seismic protection from the ground? The engineer said that sometimes it is, but usually it is not necessary to do so. He recommended using a software program that combines different types of methods, such as the Start Pro program. Another question was asked: how should we focus on different aspects of foundation, structure, and efficiency when designing with seismic isolation? The engineer said that each country should focus on its own strengths, and that Peru is no exception. He was happy to clarify any questions and thank the audience for their participation. 470 people have commented on the engineer's Facebook page, and 130 people have watched his YouTube video.
  • 01:30:00 This video discusses the importance of using seismic isolation in important buildings, and recommends that for soft soils, non-elastomeric isolators should not be used, but then we would say another thing. In Japan, the ground is bad, and using American isolators there is but one problem- Japan enjoys better earthquake pilots. Pilots can reach their natural ground better, and they have more money than we do. However, this is not always the case. There have been experiences where we have to be very careful when designing with elastomeric isolators for soft soils because movement of air or displacement is needed, and worse yet, there is no safety policy for these types of isolators with pivotable friction devices. I said earlier that deposit of gas at millions of cubic meters of gas is currently where it is most needed, and this is because Japan has taken notice of the bull's-eye that water emerged from the prison during the Ica earthquake. However, there was no problem with elastomeric isolators in that earthquake. So, this much can be solved by using the Legislature's platform. And there we place the isolators, but when there is a water-bearing shallow groundwater layer, methods of injection of concrete cycles are also available
  • 01:35:00 The video discusses the importance of seismic isolation in important buildings, and the importance of choosing a provider wisely for such isolation. The speaker mentions that they have used the same provider for all of their buildings, or have been able to find a variance that meets the efficiency goal. The speaker goes on to say that they are a hospital designer with over 20 years of experience, and that they are 100% familiar with hospital design. They say that they are Catholic and a believer in the spiritual benefits of seismic isolation, so they left university to pursue greater information on seismic isolation. They went to a laboratory specializing in seismic isolation and was the first person to do so. The doctor there told him that he had never heard of such a thing and invited him to stay for a visit. The speaker then tells the story of how they were able to find the solution, which was to use metal-friction isolators made in America by Dr. Zayas. The doctor was surprised by the Peruvian son's installation of such isolators in his hospital. The speaker says that they had always intended to achieve the goal of the law of health care safety, but that we had not been able to do so until now because of the lack of seismic isolation. The
  • 01:40:00 The importance of seismic isolation in essential buildings was discussed in this virtual seminar. All the fluctuations that the public administration is experiencing can be traced back to its redesign because, as experienced professionals, we now have a good understanding of the use of seismic isolation in general. I consider that I have given three golden rules that architects should follow when designing with seismic isolation in mind, and which are equal 1, the only disagreement that we have so far with current design practices is regarding the use of 50% reduction in earthquake resistance. Most architects teach that you should use equal 2, but I think that this is too restrictive, and that you should use ductility to solve the problem. I agree that acceleration is average, but I disagree with the engineer who said that you should use ductility instead of equal 2, because the latter would require too much structural reinforcement. In addition, I think that there is a disagreement about the drift that we all agree on, and about the average seismic acceleration in buildings of average height. We also agree that the sway is a concern, but I disagree with the engineer who says that you should use ductility to eliminate the sway. Instead, I think that you should use ductility to reduce the sway in the structure, and achieve a high quality construction
