本文通过扩展IMP法,考虑了SRSS振型组合准则中的一阶非弹性谱位移和后弹性一阶振型,提出了一种估计设置滞回阻尼器的建筑结构地震需求的简化方法。一般情况下,阻尼器的屈服顺序早于框架,第一阶振型响应采用多弹簧模型,高阶振型响应采用等效的刚度和阻尼系数。还提出了一种适合于非线性静力Pushover分析的外力分布,以适当地估计后弹性一阶振型。
In this paper, a simplified method for estimating the seismic structural demands of a building with hysteretic dampers is proposed by extending IMP, which considers the first-mode inelastic spectral displacement and the post-elastic first-mode shape in SRSS rule of modal combination. Dampers generally yields sequentially and earlier than the frame, and such behavior is considered by a multi-spring model for the first modal response and by the equivalent stiffness and damping factors for the higher modal responses. An appropriate external force distribution for a nonlinear static pushover analysis is also proposed to appropriately estimate the post-elastic first-mode shape.
