Parameter Analysis of Vehicle-Bridge Coupling of Half through CFST Arch Bridge due to Vehicle
As a new structure type, arch bridge of concrete filled steel tube (CFST) has many merits and unique dynamic characteristics. Some present researches indicate that the CFST arch bridge has obvious impact effect, but the research on its dynamic performance due to vehicle is relative backward. In this paper, power spectral density function is selected to simulate the roughness of pavement, the dynamic equation of vehicle-bridge is built with seven degrees of freedom vehicle model. Based on separated iterative method, the parameters’ influence of CFST arch bridge on dynamic performance due to vehicle is carried out systematically. The analysis results are useful and helpful for the design theory of impact effect of CFST arch bridge.
