Projects : Golden Gate Bridge Exhibit

Golden Gate Bridge Outdoor Exhibition

PROPOSED EXHIBITS

How a Suspension Bridge Works

Engineers call it a load path – the path taken by the loads (e.g. the weight of the structure and what it carries, the wind forces on it) as they flow through the structure to reach the foundation. A suspension bridge load path is basically simple, but is not apparent to non-engineers. The vertical suspender ropes pull the weight of the deck up to the main cables. The main cables carry it to the tops of the towers. The weight goes down the two towers to the foundation. The ends of the cables must be anchored to resist the tension (pulling) force that acts horizontally, inwardly, and vertically, upwardly.

STATUS: Exhibit currently installed near the Battery exhibit area.

Original design of the Suspension Bridge exhibit sign.

Note the inclusion of the various other famous bridges of the world (an idea eventually considered for its own exhibit).

Original concept by Reitherman

A revised version which includes the originally planned Art Deco styled border.

Note the inclusion of the placeholders for the lift doors. It was originally envisioned to have the one image spread across three separate doors.

Revised concept by Reitherman

Revised version by the Hunt Design based on the NPS park signs.

This version was neither completed, nor ultimately used because it was felt that the material was not presented in a clear or logical order.

With much input from the project advisors, and engineering specialist, this version was produced combining the NPS layout style, with a cleaner overall layout of information.

Title changed to: How the Bridge Spans the Golden Gate

Original version of door panel graphic w/ animals.

Note: This version was later changed when t was pointed out that the tug-of-war pose did not match the load path lesson described in the text.

Modified version of door panel graphic w/ animals.
A family visiting the Bridge stop to interact with the Suspension Bridge exhibit.
Here Bob Reitherman talks about the layout design with an audience of civil engineering professors.
