SEISMIC RESPONSE ANALYSIS OF STRAP TRAVERSE BRIDGE FRAME

Based on the analysis of strap traverse structural design at home and abroad, SAP2000 was used to make a numerical simulating analysis of Strap Traverse Bridge frame with specific engineering, and the mode analysis is carried out in dynamic characteristics of strap traverse bridge frame by using finite element method.On the basis of Modal Analysis, this paper also carried out response spectrum analysis of the Bridge frame.Considering the influences of the horizontal and vertical earthquake action of structure, 4 conditions have been analyzed in view of the dead weight of structure and seismic action in horizontal and vertical, come to the seismic response of structure under various conditions, through the analysis to get the corresponding conclusion, proposed the rationalization proposal for seismic design of strap traverse bridge frame.The research has a certain theoretical significance and engineering use value.
