Abstract

In order to study the influence of large temperature difference on the seismic performance of cable-stayed bridge, a cable-stayed bridge with a temperature difference of 105m+240m+105m was used as the background, and the concrete axial compression tests were carried out at 40℃, 20℃ and -30℃ respectively, and the material characteristics of concrete and steel were obtained at three temperature conditions. Using Opensees finite element software, a fine nonlinear finite element model of the bridge under global temperature is established, and the seismic vulnerability of the bridge under different temperatures is studied based on IDA method. The results show that the seismic vulnerability of the bridge tower under different temperature conditions shows that the bridge tower is greatly affected by temperature, and its failure probability increases with the decrease of temperature. When designing such Bridges in areas with large temperature difference, the effect of low temperature on the seismic performance of the Bridges should be considered.
