摘要:
提出了内藏桁架(包括钢桁架、钢筋桁架及钢-钢筋组合桁架)混凝土组合剪力墙,该新型组合剪力墙包含2种组合:不同受力体系,桁架与剪力墙的组合; 不同材料,型钢与混凝土的组合,形成了双重组合剪力墙.进行了6个1/3缩尺的剪力墙的抗震性能试验研究,包括普通混凝土剪力墙、内藏钢框架混凝土剪力墙、内藏钢筋桁架混凝土剪力墙、内藏钢框架-钢筋桁架混凝土剪力墙、内藏钢桁架混凝土剪力墙及内藏钢-钢筋组合桁架混凝土剪力墙.在试验研究基础上,对比分析了各剪力墙的刚度及其衰减过程、承载力、延性、滞回特性、能耗及破坏特征.试验表明,内藏钢框架及内藏不同材料桁架混凝土剪力墙的抗震性能比普通混凝土剪力墙明显提高.建立了内藏桁架混凝土剪力墙的承载力计算模型,计算结果与实测结果符合较好.提出了该新型剪力墙抗震设计的建议.
Abstract:
Shear wall with concealed truss is brought forward. This concealed truss can be constructed with profiled steel, steel bar or profiled steel appending steel bar. This new composite shear wall includes two kinds of composition. One is composition of two bearing systems, including truss and shear wall, the other is composition of two materials, including steel and concrete. The experimental study on the seismic behavior of six 1/3 scale shear walls, including a usual shear wall, a shear wall with steel frame, a shear wall with steel bar truss, a shear wall with steel frame and steel bar truss, a shear wall with steel truss and a shear wall with steel and steel bar truss, were carried out. Based upon the experimental study, the stiffness and its attenuation, load-carrying capacity, ductility, hysteretic property, energy dissipation and failure phenomena of each shear wall are contrastively analyzed. The experimental results show that the seismic behavior of the shear wall with steel frame and every truss with different materials is obviously improved. The formulas of load-carrying capacity are established. The results obtained from the formulas and those from experiment are in good agreement.Finally, some suggestions for seismic design of this new shear wall are proposed.
