| Abstract: | Taking a single-pylon double-plane composite beam(composed of combined beams and concrete beams) cable-stayed bridge as the engineering background,the article analyzes the dynamic characteristics of this bridge.Based on the theory of the finite element method,the article determines the space calculation model of this bridge,and on this basis,studies the seismic performance of this bridge by the application of response spectrum method. |
