为研究钢框架-预制混凝土抗侧力墙板装配式结构体系(SPW体系)的抗震性能,对2榀钢框架-预制混凝土抗侧力墙板结构足尺试件进行拟静力荷载作用下的试验研究。试验结果表明:该结构体系为一种典型的双重抗侧力体系,加载过程呈现出明显的两阶段性,抗侧力墙板为结构体系的第一道防线,钢框架为结构的第二道防线;基于纤维单元,利用CANNY软件建立SPW体系的有限元模型,在验证模型正确性的基础上,分析了框架柱刚度、框架梁刚度、墙体高宽比和墙体内置型钢含钢率等因素对SPW体系墙抗震性能的影响,分析结果表明:结构体系的塑性耗能性能主要是由抗侧力墙和框架梁端的耗能决定的;随着墙体高宽比的减小,结构的耗能性能和延性变差。增大墙体内置型钢含钢率有助于提高结构的耗能性能。
In order to study the seismic behavior of steel frame-prefabricated anti-skid panel assembly system (SPW system), the effect of pseudo-static load on two-story steel frame-prestressed concrete Experimental Research. The test results show that the structure is a typical double anti-lateral force system, and the loading process shows obvious two-stage. The anti-side-force panel is the first line of defense of the structural system and the steel frame is the second Based on the fiber unit, the finite element model of the SPW system was established by CANNY software. Based on the verification of the correctness of the model, the stiffness of the frame column, the stiffness of the frame beam, the aspect ratio of the wall and the steel content rate of the built-in steel wall The results show that the plastic energy dissipation of the structural system is mainly determined by the energy dissipation of the anti-side wall and the frame beam. As the aspect ratio of the wall decreases, the structural Energy dissipation and ductility deteriorate. Increasing the steel content of the built-in steel wall can help improve the energy dissipation performance of the structure.
