FREE VIBRATION OF STIFFENED CIRCULAR BRIDGE DECKS

An analytical method for determining the free vibration frequencies of stiffened curved bridge decks is presented. The bridge deck is idealized as a system consisting of a number of concentric annular plate and circular ring segments rigidly connected to each other. From the closed form solutions for free vibration of the individual plate segments and rings, the frequency of the system is obtained by imposing the edge and continuity conditions. Results for several cases are furnished and a comparison with experimental results is also presented. (A) /TRRL/
