摘要:
为研究框架摇摆墙结构体系的抗震性能, 以1个6层混凝土框架结构模型为例,利用通用有限元软件SAP2000建立了该结构的简化模型,并通过弹塑性动力时程分析, 得到了附加摇摆墙前后结构的地震响应。分析结果表明:附加摇摆墙后,结构以摆动振型振动,各层的层间位移角趋于一 致,结构层间变形的集中得到有效控制,从而使结构形成整体屈服破坏机制,防止局部层屈服破坏机制的产生,充分发挥整 个结构的耗能能力; 附加摇摆墙后,结构周期略有减小,不会显著增加结构基底剪力,即使仅附加高度为结构总高度一半 的摇摆墙,也能有效控制结构底层的变形集中; 该框架摇摆墙结构体系具有良好的抗震性能。
Abstract:
The seismic responses of a 6-story reinforced concrete(RC)frame with and without the rocking-wall were compared using the elastic-plastic time history analysis by general finite element software SAP2000. The analysis results show that this system is forced to vibrate on a rocking mode during the earthquake. The failure mechanism of this structure is overall yielding mechanism instead of story yielding mechanism when it gets damaged. The overall yielding mechanism endows satisfactory energy dissipation capacity of the structure. The story drift becomes more uniform distributed and the deformation concentration phenomena significant improved thanks to the rocking-wall. The first story drift can also be effectively controlled even if the additional height of rocking-wall only reaches half of the entire height of structure. The RC frame rocking-wall structure system has satisfactory seismic performances.
