Research and Understand How Structures Behave
On November 7, 1940 the Tacoma Narrows Bridge in the State of Washington vibrated violently in a 42-mile-per-hour wind. The oscillations became so severe that the bridge literally shook itself apart. This incident sparked a surge of research into the cause, and engineers using solid mechanics theory discovered how the movement of a fluid over a structure can cause serious vibrations. Knowledge gained through this research has led to design principles for modern bridges to avoid such wind-induced failure.
