EFFECT OF ROTARY INERTIA AND SHEAR ON NATURAL FREQUENCIES OF CANTILEVER BRIDGES

A study of the natural frequencies of cantilever bridges including the effects of rotary inertia and shear deformation is presented. The bridge is assumed to act as A series of elastic beams with distributed mass. Frequency equations are derived for the symmetric and the antisymmetric vibrations. Values of the frequency parameter owing to the rotary inertia and shear effects are presented and are compared with those obtained by classical analysis. (A) /TRRL/
