Seismic Analysis of Long Span Bridge Considering Topography Effect with Oblique Incidence of SV Wave
In this paper, the explicit finite element method to solve single-phase elastic solid media nodal points dynamic response with incidence of SV wave is introduced, Combined with local transmitting artificial boundary, the finite element method which can be used to simulate dynamic response analysis of single-phase elastic media of any topography when obliquely incident SV wave happened. With this method, the ground seismic response of an irregular topographic site is computed, and the related seismic ground motion is input to long span bridge,the seismic response of long span bridge considering asynchronous excitation is also computed. The effect of the change of incident angle and height/width ratio to earthquake response of ground surface and long-span bridge is analyzed, and some preliminary conclusion is concluded. It can be referred when the long-span structures which suffered asynchronous excitation is built through the irregular topography.
