摘要
钢框架—预制混凝土抗侧力墙装配式结构体系(SPW体系)为一种典型的双重抗侧力装配式体系,抗侧力墙体为结构体系的第一道防线,钢框架为结构的第二道防线。为研究该体系的受力机理和受剪承载力,在试验研究的基础上建立了钢框架与抗侧力墙体基于协同效应的传力机制,对抗侧力墙体的受力机理进行了分析,提出了该结构体系在各受力阶段的简化计算模型,推导受剪承载力的计算公式,并同试验值进行了对比分析,可靠性较好。
A steel frame-concrete lateral-force-resisting-waU fabricated structure is a kind of typical double lateral force-resisting fabricated system, the concrete lateral force-resisting wall is the first line of seismic defense for the structural system, and the steel frame is the second line of seismic defense. In order to research the mechanical performance and shear bearing capacity of the structure, the force-transferring mechanism based on synergistic effect between a steel frame and concrete lateral force-resisting wall was proposed on the base of experimental studies, and the mechanical performance of concrete lateral force-resisting wall was analyzed. The simplified calculation models at every loading stage were suggested and the formulas of shear bearing capacity were derived, which has good reliability compared with experimental results.
