Seismic Response Analysis of Prestressed Concrete Bridge

Abstract:

Using large-scale finite element analysis software ANSYS analyzes seismic respons of prestressed concrete bridge, respectively establish finite element model under viscoelastic boundary conditions and elastic boundary conditions, compare and analyze seismic respons of bridge structure under two kinds of boundary conditions. Compared with elastic boundary conditions, viscoelastic boundary conditions not only can simulate elastic recovery performance of foundation, but also can realize infinite medium radiation damping. The research results provide the basis for the seismic design and protection of bridge.
