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。
Low-cycle reciprocating quasi-static tests were carried out on 10 scaled specimens with double-steel-concrete composite shear walls in a nuclear power plant’s shield factory. The influences of such factors as plate thickness, stud spacing, vertical load and stiffener setting Effect of double steel concrete composite shear wall flexural capacity. The analysis results show that the thickness of plate, vertical load and the setting of stiffeners all have great influence on the flexural capacity of shear walls, while the spacing of studs has little effect on it. The ABAQUS finite element software was used to simulate the double steel-concrete composite shear wall specimens. The results of the finite element analysis and the experimental results show that the two are in good agreement with the flexural bearing capacity, but the finite element method There is no obvious drop in the curve. Combining with the experiment and finite element numerical simulation, the formula of flexural capacity of double steel-concrete composite shear wall is proposed. The research provides a theoretical basis for the design and application of double steel-concrete composite shear walls in the future.
