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 row of steel concrete column shear wall specimens and a row of steel concrete column - block steel shear wall specimens were designed and tested by low cycle repeated loading test. The failure characteristics of each specimen were analyzed , The bearing capacity, the hysteretic performance, the stiffness attenuation process, the ductility and the energy dissipation capacity etc. The analysis of the test results shows that the seismic performance of the concrete slab wall with continuous row of steel-concrete columns combined with shear wall is significantly improved The formula for calculating the stiffness and bearing capacity of the combined shear wall of the steel reinforced concrete column with the slab steel plate is established, and the calculation results are in good agreement with the experimental results.
