摘要:
在已有试验研究的基础上,采用平面非线性软件IDARC 2D建立数值模型,对一棍配置核心钢管的混凝土柱和钢骨混凝土梁新型组合框架进行滞回分析,并与试验结果对比.同时,对此框架的套建增层改造实例进行地震反应时程分析.研究结果表明:IDARC 2D能较好地模拟组合框架在低周往复荷载作用下的受力过程,为此类框架滞回性能的模拟提供了合适的方法;此新型框架具有梁较耗能,延缓柱底出较的特点,抗倒塌能力较强．
Abstract:
In this study,a theoretical research on hysteretic behavior of a new composite frame composed ofRC column encased steel-tube and steel reinforced concrete beam was proposed by using the plane nonlinearsoftware-IDARC2D. The theoretical analysis results were compared with experiments. In addition,seismic re-sponse regarding to an outer-jacketing reconstruction example of composite frame was analyzed by means oftime-history analysis. The research results showed that IDARC 2D could preferably simulate the entire loadingprocess on the composite frame,and provide a suitable analytical method for hysteretic behavior. The emer-gence sequence of plastic hinges on this frame is ‘beam ends before and column bottoms after’,so that theanti-collapse ability of the structure was largely enhanced.
