方钢管混凝土柱-钢梁平面框架抗震性能试验研究
|
摘要
进行了3榀方钢管混凝土柱-钢梁平面框架的低周反复加载试验,分析了轴压比和梁柱线刚度比对框架抗震性能的影响。得到了框架的荷载-位移滞回曲线、骨架曲线及各阶段的荷载和位移值,分析了框架的破坏特征、延性、耗能能力、承载能力及刚度退化。试验结果表明:框架滞回曲线饱满,具有良好的变形性能和耗能能力;增大轴压比将降低框架的延性和水平极限承载力,提高框架的耗能能力;增大梁柱线刚度比将降低框架的延性和耗能能力,提高框架的水平极限承载力。试验结果可为方钢管混凝土柱-钢梁框架的工程应用提供参考。
A total of 3 pseudo-static experiments were conducted for three planar experimental specimens.The influence of axial load ratio and linear stiffness ratio of steel beam to column on the frame seismic behavior was investigated.The load-displacement hysteretic loops,skeleton curves and the load and displacement values for different loading stages were obtained.The failure characteristics,ductility,energy dissipation capacity,load carrying capacity and stiffness degeneration were studied.The experimental results show that the load-displacement hysteretic loops are stable,and the deformation properties and energy dissipation capacity are adequate.Increasing the axial load ratio decreases the frame ductility and lateral load ultimate capacity,but leads to higher energy dissipation capacity.With the increase of the linear stiffness ratio of steel beam to column,the ductility and energy dissipation capacity become low,but the lateral ultimate capacity becomes high.Test results provide a reference for the engineering application of concrete filled square steel tube columns and steel beam frames.
