|
摘要
针对钢筋混凝土框支剪力墙抗震性能差的缺点,提出采用型钢混凝土框支剪力墙.进行了4榀模型试件拟静力试验,试验结果表明,结构配置型钢后抗震性能得到显著改善.提出了框支剪力墙结构地震反应简化分析模型,将结构简化为由墙单元和框支单元组成的弹簧体系,给出了单元恢复力模型的确定方法.根据简化模型,编制了结构地震反应时程分析程序,并进行参数分析,研究了配置型钢对结构地震反应的影响,给出了型钢混凝土框支剪力墙弹塑性位移的实用计算方法.
The frame with steel reinforced concrete is proposed to replace the frame with reinforced concrete frame to improve the seismic behavior of the structure of shear wall.An experimental investigation for the four specimens was conducted to study the behavior of the proposed structure subjected to simulated seismic load. The experiment results show that the system of shear wall supported by frame reinforced with steel members presents itself a strong capability for earthquake-resistance.A simplified analysis model for seismic response of this type of structure is presented,the model consists of elements of wall and elements of frame-supporting,and the restoring models of the elements are also given.Based on the simplified model,the time history response program is developed.The effect of the steel for the structural seismic response is discussed.A practical approach for estimating elastoplastic displacement of the structure of shear wall supported by frame with steel reinforced concrete is finally presented.
