000009678 520__ $$2eng$$aThe seismic behavior of a long-span arch bridge is investigated based on a series of nonlinear dynamic analyses. The bridge was modeled with ADINA by means of elements with nonlinear behavior Since the axial force and bending moment interaction is significant in the arch rib under strong ground motions, this effect is included in the analyses by frame elements varying their moment-curvature relations. It was found from the analyses that large axial forces, as much as 1.5 times the dead axial force are developed in the arch rib during excitations, so moment-curvature relations change in the arch rib and hence should be considered in design.
