Dynamic Elasto-Plastic Analysis of 300m Span and 0.15 Rise-Span Ratio Arch Truss by Ninghe wave
In this paper,elasto-plastic dynamic response analyses of 300m span arch trusss structure model are carried out under the condition of earthquake by using SAP2000.The geometric and material nonlinear effects are considered.Based on the plastic-hinge theory,by gradually increasing the peak acceleration of earthquake,the structures dynamic elasto-plastic analysis have been done with Ninghe wave under the initial condition that the arch trusss stress and strain are caused by constant load and snow.According to simulation results,the critical peak acceleration is obtained when the steel framework lose stability,which can judge the anti-seismic capacity of the structure.
