Abstract

The seismic capability of concrete filled steel tube (CFST) arch bridge is determined by the arch ribs. In this paper, the seismic capacity of arch ribs is evaluated by using the method based on the strength and ductility. First, the internal forces are calculated respectively by using finite element method under gravity action and small earthquake. Then, the ultimate bearing capacities, the ratio of ductility and reduction coefficient are obtained according to the failure modes. Finally, the acceleration of ground movement and seismic capability of arch ribs are obtained. Taking a CFST arch bridge as an example, the results show that the method is efficiency for evaluating the seismic capability of CFST arch ribs under earthquake and has important the reference value.
