【摘要】：开展了核电厂屏蔽厂房双钢板混凝土组合剪力墙的结构形式的10个缩尺试件低周往复拟静力试验,研究了钢板厚度、栓钉间距、竖向荷载以及加劲肋设置等因素对双钢板混凝土组合剪力墙受弯承载力的影响。分析结果表明:钢板厚度、竖向荷载和加劲肋的设置都对剪力墙的受弯承载力有很大的影响,而栓钉间距对其影响不大。采用ABAQUS有限元软件对双钢板混凝土组合剪力墙试件进行了数值模拟,通过比较有限元计算结果和试验结果发现两者在受弯承载力上能够较好吻合,但有限元计算得出的曲线没有明显的下降段。结合试验和有限元数值模拟,提出了双钢板混凝土组合剪力墙受弯承载力的计算公式。研究为以后双钢板混凝土组合剪力墙的设计应用提供理论依据。
[Abstract]:Ten low-cyclic pseudo-static tests were carried out on 10 scale specimens of double-steel-plate concrete composite shear wall in the shielding workshop of nuclear power plant. The effects of steel plate thickness, bolt spacing, vertical load and stiffening rib setting on the flexural capacity of double-steel-plate concrete composite shear wall were studied. Both directional load and stiffening rib have great influence on the flexural capacity of shear wall, but the spacing of bolts has little effect on it.The numerical simulation of the shear wall specimens with double steel plate and concrete composite is carried out by using ABAQUS finite element software.The results of finite element calculation and test show that the two methods are comparable in the flexural capacity. The results are in good agreement with each other, but the curves calculated by finite element method have no obvious descending section. Based on the experiment and finite element numerical simulation, the formulas for calculating the bending capacity of double-plate concrete composite shear wall are proposed.
