| Abstract: | Three methods for calculating dynamic performance of suspension bridges are compared.With a single-tower self-anchored suspension bridge as an example,the finite element program ANSYS is adopted to establish the spatial computation model,calculate the natural vibration frequencies and modes of the bridge,and analyzes the effects that change the span ration to influence of dynamic performance analysis for single-tower self-anchored suspension bridge.This paper can offer reference to the dynamic analysis of t... |
