摘要
设计了1个连排型钢混凝土柱组合剪力墙试件和1个连排型钢混凝土柱-分块钢板组合剪力墙试件,进行了低周反复荷载试验研究.分析各试件的破坏特征、承载力、滞回性能、刚度衰减过程、延性和耗能能力等抗震性能.试验结果分析表明,连排型钢混凝土柱组合剪力墙混凝土墙体内加设分块钢板后,抗震性能显著提高.建立了连排型钢混凝土柱-分块钢板组合剪力墙的刚度和承载力计算公式,计算结果与试验结果吻合较好.
A composite shear wall specimen with paralleled steel reinforced concrete(SRC)columns and a composite shear wall specimen with paralleled SRC columns and concealed partitioned steel plates were designed for low cyclic loading experiment.The following factors of the two specimens were studied:failure characteristics,bearing capacity,hysteretic characteristics,process of stiffness degradation,ductility and energy dissipation.The results show that the core system with paralleled SRC columns-concealed partitioned steel plates has good seismic behavior.A formula for calculating the stiffness,bearing capacity and inclined section bearing capacity of composite shear wall with paralleled SRC columns-concealed partitioned steel plates was proposed,and the calculation results agreed well with the experimental results.
