Golden Gate Bridge

Introduction The Golden Gate Bridge is a suspension bridge connecting San Francisco to Marin Country over the Golden Gate channel. The bridge’s construction began on January 5th, 1933 and the bridge was finished and open to public on May 28th, However, the idea of having a bridge from San Francisco to Marin Country was proposed as early as The reason why I chose this bridge as my structure was because this bridge is famous enough to become one of the Seven Wonders of the World and is American (which is where I am from) so personally, I am proud of my country since they have created something big enough to achieve that big of a title. At the same time, this bridge is 8,891ft (2,737.4m) long which is pretty impressive for a bridge to be that long and to not have fallen down. This just gives anyone a good idea of how great the design for this bridge must have been especially when it was made all the way back in 1933.

How it Works The Golden Gate Bridge is made of mainly steel and has two main towers that connect two main cables to each other and those two cables string multiple vertical cables that connect with the base of the bridge. By doing this, the load is then transferred into the two main towers of the bridge and the force is then compressed down against the two towers. That way, there is an energy transfer from the base into the towers where the energy is then pushing down onto the towers and creating tension against them.

Conclusion Just from learning about this bridge, I learned a new way of creating bridges and that way is by the suspension bridge. The Golden Gate Bridge happens to be a suspension bridge that uses these tactics to hold not only the massive weight from itself but also the weight from ongoing vehicles and pedestrians. This tactic of creating bridges is the most efficient tactic that I know so I will most likely use the method that was used on the Golden Gate Bridge onto any of my structures for my own advantage.
