Wind blowing across (transversely to) the deck of a suspension bridge can make it begin to twist a very undesirable type of structural response. This exhibit mounts two similar scale-model bridge decks next to each other. One is aerodynamically superior to the other in subtle ways that make it stable in the breeze. The other noticeably twists. The Golden Gate Bridge has been extensively studied analytically and in wind tunnel testing to evaluate its wind performance.
STATUS: Exhibit currently on display on the East Battery Trail.
