Research Abstract |
An accurate pseudo-dynamic experiment was carried out to investigate the ultimate behavior of thin-walled steel bridge piers subjected to multi-directional seismic excitations as well as to confirm the accuracy of a proposed onlinear dynamic FEM shell analysis. Then, an ultimate interaction curve expressed in terms of restoring force and moment components was derived to identify the ultimate state of piers. Finally, an extensive dynamic analysis under various bi-directional seismic excitations and 3D shaking table test were carried out to confirm the accuracy of the proposed ultimate interaction curve.
