000010665 520__ $$2eng$$aThe differential quadrature element method (DQEM) is applied to computation of the eigenvalues of small amplitude natural vibration for continuous horizontally curved girder bridges with rigid piers in this paper. The DQEM uses the differential quadrature technique to discretize the governing differential eigenvalue equations defined on each member, the transition conditions defined on the inner-element boundary of two adjacent members and the end conditions of the continuous curved girder. Natural frequencies are calculated for a two-equal-span, continuous, curved, uniform girder bridge, and are compared with existing exact solutions by another method. Finally, parametric results for the effects of section gyration radius and flexure-torsion stiffness ratio on five different end conditions, to the out-of-plane natural frequencies of two-equal-span, continuous, curved girder bridges, are presented in dimensionless form.
