摘要:
为了能够在往复推覆分析中考虑结构能量耗散历程特征的影响,首先根据结构单向耗能能力曲线和耗能需求曲线的交点确定结构在相应地震作用下的延性需求与最大瞬时变形能需求,进而由延性需求得结构的累积滞回耗能需求:其次在已知最大瞬时变形能、累积滞回耗能和能量增长持时的基础上,根据简化模型获得结构变形能耗散历程曲线,该曲线从能量的角度综合体现了地震对结构的峰值效应、累积效应和历程效应,从而实现完全以能量为推覆控制目标的静力非线性分析。研究表明:该往复推覆分析方法能够较为准确的估计钢筋混凝土框架结构在地震作用下的最大层间位移、累积滞回耗能以及滞回耗能在构件中的分布状况。
Abstract:
In order to consider the course characteristics of seismic energy dissipation during the pushover analysis, the intersection point of structural energy dissipation capacity curve and energy dissipation demand curve is found to indentify the ductility demand and maximum instantaneous strain energy demand. Then the total hysteretic energy demand can be calculated by the ductility demand. Based on the maximum instantaneous strain energy demand, total hysteretic energy demand and energy growth duration demand, the strain energy dissipation course curve which reflects the peak effect, cumulative effect and history effect of ground motion to structure will be calculated by a simplified model to realize the cyclic pushover analysis. The cyclic pushover analysis method based on strain energy dissipation course curve can accurately estimate the maximum deformation, total hysteretic energy and hysteretic energy distribution in the structural members.
