摘要

对阻尼支撑框架结构的弹塑性时程分析方法进行了探讨,给出了阻尼支撑的力学计算模型;对地震动的选用进行了分析,给出了地震动选取的初步建议。建立了两个三层的单榀粘滞阻尼支撑框架结构,利用IDARC 2D非线性分析软件进行了弹塑性时程分析,对框架弹塑性阶段的地震响应、塑性铰分布及结构损伤进行了对比研究,提出了阻尼支撑框架结构的设计要点,为实际工程提供设计依据。
In this paper,the nonlinear time history analysis of structure braced with viscous dampers is discussed.The mechanics model of the brace and the damper is presented,an analysis about the selection of ground motion is made,and the advice of the selecting method is put forward.The model of two-plane-frame structure with three stories,braced with viscous dampers is built.We use IDARC 2D to make nonlinear time history analysis,and this software is accomplished in nonlinear analysis.We research the seismic response,distribution of plastic hinges and damage of structure when frame is in plastic phase,then we point out the design essentials of this kind of structure,and make it a gist for the practical engineering.
