Analysis on Long-Span Bridge Seismic Response in Multi-Dimensional and Multi-Point Mode
The Seismic excitation mode has been the hot and difficult topic both in engineering and academic field. This paper mainly discussed the excitation direction and the combination of excitation direction of ground motion, comparatively analyzed seismic response in four excitation mode, which including the single-track one-point incentive, single-track multi-point incentive, much-track one-point incentive, and much-track multi-point incentive, with specific project examples of large-span continuous rigid frame bridge, and get the corresponding conclusions.
