Summary of Golden Gate Bridge | The CRAZY Engineering behind it

00:00:00 - 00:15:00

The Golden Gate Bridge is a suspension bridge in San Francisco, California. It was built in the 1930s and is one of the most famous and successful bridges in the world. The engineering behind it is impressive, and the construction was a major accomplishment at the time.

• 00:00:00 The Golden Gate Bridge is a suspension bridge built using a design of Joseph Strauss. If the suspension cables were not present, the bridge would collapse due to the tension on the cables. Strauss solved the problem of the connections between the suspenders and the steel structure by using a steel to steel connection. The bridge is able to handle a lot of traffic due to its small width and the fact that the towers are close to one another.
• 00:05:00 The Golden Gate Bridge was built using a derrick and rivets to secure the laborers, suspension cables were used to connect the bridge with the main cable, and finger expansion joints were used to address thermal expansion issues. The bridge was painted a special international orange color and thermal expansion was addressed by installing tiny expansion joints every 50 feet.
• 00:10:00 The construction of the south side tower of the Golden Gate Bridge was tougher than the north tower due to the south tower's construction having to overcome the violent Pacific Ocean. Professional divers were hired to blast bombs underwater to create a foundation for the south tower, and the divers cleared the debris of the explosion and made a better surface. The divers then constructed a steel and wooden framework on this surface, and the workers reached the hard strata using the workers' shaft. The construction of the complete foundation is quite easy now, and you can see how the fender walls protect the main foundation from the deadly waves. After laying the main cables, the workers constructed a catwalk bridge for themselves at first, and then laid a support wire. The main cables were passed over the tower through the cable saddles one by one and were then clamped by laborers. The workers then pressed the wires tightly using a hydraulic press and wound the wires together using galvanized steel wire. The main cable looks like a single large pipe, and the cables are anchored to the bedrock with strand shoe steel plates. After laying the main cables, the suspension cables were attached to it. All that was left to do was construct the deck structure and lay down concrete for the road.
