提出了一种钢管混凝土边框内藏分块钢板的双肢剪力墙,通过低周反复荷载试验研究其抗震性能,分析了各试件的破坏特征、承载力、滞回特性、耗能和墙底截面的应变分布情况。研究表明:内藏分块钢板的加设可大幅提高双肢剪力墙的承载力和耗能能力,刚度也得到了提升,充分发挥了钢管、型钢、钢板与混凝土墙体共同抵抗地震作用的效能。根据试验结果,建立了钢管混凝土边框内藏分块钢板双肢剪力墙的承载力计算公式,计算结果与试验结果吻合.
A two-limb shear wall with steel plates and steel plates embedded in the steel plate is proposed. The anti-seismic performance of the concrete-filled steel tubes is studied by cyclic loading test. The failure characteristics, bearing capacity, hysteresis characteristics, Bottom section of the strain distribution. The research shows that the addition of built-in sub-slab steel plates can greatly increase the bearing capacity and energy dissipation capacity of double-limb shear walls, and the rigidity has also been improved, giving full play to the role of steel pipe, steel plate, steel plate and concrete wall together to resist the earthquake efficacy. According to the test results, the formula for calculating the bearing capacity of two-legged shear wall with steel plates and concrete slabs is established. The calculation results agree well with the experimental results.
