【Abstract】 Based on the engineering background of a continuous rigid frame bridge,the finite element model of the whole bridge is established based on ANSYS,and artificial seismic waves are generated from the standardized response spectrum.The seismic response time history of the structure is analyzed by direct acceleration method and large mass method respectively.The analysis method and research results can be used for reference in practical engineering.更多还原
