基于普通混凝土钢板剪力墙的构造形式及受力特点,本文提出了以预制水泥基轻型混凝土板作为钢板两侧保护墙板的新型组合钢板剪力墙。针对预制水泥基轻型混凝土板—钢板组合剪力墙的构造形式、抗侧刚度、抗震性能及破坏特点等方面进行了五个试件的水平推覆试验研究。结果表明,较大宽厚比钢板会产生较大的平面外变形,极限抗剪承载力较低;预制墙板对钢板的抗侧刚度及屈曲荷载都有所提高;钢板的约束形式对结构耗能、钢板屈曲形式及墙板破坏形式有较大的影响。
Based on the structure and force characteristics of ordinary concrete shear wall, this paper presents a new type of composite shear wall with prefabricated cement-based lightweight concrete slab as the protective wallboard on both sides of the steel plate. In this paper, the horizontal pushover test of five specimens in precast cement-based lightweight concrete slab-steel composite shear wall structure, lateral stiffness, seismic performance and failure characteristics were studied. The results show that the larger width-thickness than the steel plate will produce large out-of-plane deformation, the ultimate shear capacity is lower; prefabricated panels on the steel side stiffness and buckling load have increased; the constraint form of steel plate structure energy consumption , Steel buckling forms and the form of wallboard damage have a greater impact.
