ABSTRACT
In this paper, the combined method of finite element numerical simulation and field measurement is used to analyze the influence of boundary conditions, diaphragm spacing, and crossbeam spacing on the dynamic performance of composite curved beam bridge with corrugated webs. The results show that the torsional stiffness of the structure is significantly higher than the vertical and lateral bending stiffness, and the vertical bending stiffness is the lowest. The influence of the end diaphragm on the dynamic characteristics of the structure is greater than that of the middle diaphragm. For the double-girder bridge, the influence of crossbeam at the end position is greater than that in the middle. The maximum dynamic strain value shows that the outer position of each steel box girder is significantly higher than the innerand the dynamic strain value tends to decrease first and then increase with the increase of the vehicle speed.
