SEISMIC RESPONSES OF THE PARTIALLY CONCRETE-FILLED ARCH BRIDGE AND A PERFORMANCE EVALUATION METHOD
This paper presents the seismic response behaviors of a deck-type steel arch bridge composed of stiffened box-section concerning the effect of the widthtothickness ratios obtained from linear buckling theory. The simulated transverse ground motion specified by the Japanese Society of Steel Construction (JSSC) was applied to the three-dimensional (3-D) nonlinear seismic analysis. The application of concrete-filled section applied to the base locations of the arch ribs was introduced to improve the seismic behaviors. The seismic responses of the partially concretefilled arch bridge and the distribution of yielded elements were compared to the case of stiffened box-section models. The numerical results indicated that the application of concrete-filled section can reduce the axial compressive force response and strain response generated in their own members as well as the displacement response at the arch crown. The proposed seismic performance method was eventually brought to investigate the failure criterion in the yielded elements developed during the transverse excitation of the arch bridges.
