Space Seismic Response Analysis of City Elevated Curved Box Girders Bridge
Taking an engineering design case about a city elevated curved box girders bridge, the dynamic calculating model of the curved box girders bridge is created by the finite element analysis program ANSYS. The analysis of curved box girders bridge with space seismic response are discussed, and a time history analysis is conducted for the curved box girders bridge subjected to the E1 Centro earthquake waves in two conditions.The internal force and the displacement time history response curve of the curved box girders bridge are obtained. The results indicate that the seismic response of curved box girders bridge with three-dimensional earthquake are bigger than two-dimensional, and consider the vertical seismic have considerable influence on the axial force of bridge piers, the internal force and displacement of box girders.
