摘　　要：提出并阐明了自减震房屋的概念;对现有典型的自减震构件的类型及构成等进行了综合分析,在此基础上,设计了自减震房屋算例并进行了强震下的整体结构地震响应分析以考察自减震房屋的可行性。主要结论如下:将减震技术融合到房屋的部分构件中,形成自减震房屋的概念和原理可行,具有可实施性;自减震房屋的实现关键在于自减震构件的设计,根据工程实际,可选取填充墙、楼梯、连梁、节点等不同类型的构件中的一种或多种作为自减震房屋减震构件设计的方向;阻尼填充墙(DIW)和消能减震楼梯(EDS)是构成自减震房屋可供选择的其中两种自减震构件,在地震作用下可发挥良好的消能作用,起到显著的减震效果;合理设计的自减震房屋在强震作用下的地震反应较传统房屋大为降低,其中,层间位移角和基底剪力的降幅达26%以上。The concept of self-seismic reduction building was advanced and clarified.The types and the construction schemes of the advanced self-seismic reduction components were analyzed comprehensively,on these basis,an example of self-seismic reduction building was designed,and the seismic response of the designed self-seismic reduction building under strong seismic motion was analyzed so as to study the feasibility of self-seismic reduction building.The main conclusions are as follows:the concept and the principle of constructing self-seismic reduction building by making some components of the building owning seismic reduction properties are feasible and practicable;the key of the realization of self-seismic reduction building was the design of self-seismic reduction components,according to engineering practice,one or more building components,such as infill wall,staircase,coupling beam and joints,et al,can be selected as the design direction of self-seismic reduction component;DIW and EDS are two types of self-seismic reduction components which can be chosen,under seismic motions,DIW and EDS can play a good role in energy dissipation and achieve significant seismic reduction effect;the seismic response of self-seismic reduction building designed rationally under strong earthquake was much less than the traditional building,and the decreasing amplitude of story drift and base shear force can reach above26%.
