| 摘 要： | 基于能量分析原理提出了一个建筑结构的塑性损耗指标,即结构的塑性损耗能在总输入能中的比例,用来衡量建筑结构在地震载荷作用下的实际损伤程度.通过有限元软件ABAQUS运用非线性动力弹塑性分析方法分析了一个典型框架—核心筒超高层结构.计算了该结构在同一地震波不同地震强度下的塑性损耗指标、构件和层的塑性损耗能分配,以及在不同地震波同一地震强度下的塑性损耗指标、层塑性损耗能分配；模拟了该结构相应的损伤破坏分布情况.两种方法表征的结果趋势一致,表明结构的塑性损耗指标和塑性损耗能分配可用来衡量结构整体和局部塑性损伤破坏情况.

| Abstract: | Based on the energy analysis principle,a structural plastic damage index was proposed,which is defined as the ratio of structural inelastic energy to total input energy.The index can be used to estimate structural damage under earthquake load.Seismic simulation of a typical super high-rise frame-tube structure was carried out by conducting a nonlinear dynamic time history response analysis using ABAQUS.The structural plastic damage index and plastic dissipated energy distribution along storeys and in differ... |
