Study on Seismic Performance of Precast Segmental Self-Centering Concrete-Filled Steel Tubular Bridge
In order to further understand the application effect of this construction technology in modern bridge construction,this paper takes a bridge project as an example to simulate and analyze the seismic performance of precast segmental self-centering concrete-filled steel tubular bridge by means of finite element analysis.Firstly,the basic situation of a road and bridge project is briefly introduced,then the bridge structure model is established,and the seismic performance of the bridge under different working conditions of vertical axial compression ratio,steel pipe wall thickness,initial prestress,core concrete strength,and energy-dissipating reinforcement ratio is simulated and analyzed,so as to provide a reference for the construction of precast segmental self-centering concrete-filled steel tubular bridge.
