【摘要】 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。更多还原

【Abstract】 Based on the concrete-steel plate shear wall,the innovative composite(precast cement-based light concrete plate-steel plate) shear wall is presented in this paper.Formation,lateral stiffness,seismic behavior and failure mode of the composite shear walls are studied by experiments.The results indicate that the steel plate with larger width-thickness ratio has larger out-of-plane distortion and smaller shear-carrying capacity;the lateral stiffness and buckling load of the composite shear walls would be enhanced by the precast cement-based light concrete plate connected to the steel plate;the energy dissipation capacity of structure system,the buckling mode of the steel plate,and the failure mode of the precast concrete plate would be influenced by the constraint condition of the steel plate.更多还原
