【摘要】：为了研究核电工程双钢板混凝土组合剪力墙在面外荷载作用下的抗震性能,本文对6个剪力墙试件进行了低周往复荷载试验。制作的试件包括5个双钢板混凝土组合剪力墙试件和1个钢筋混凝土剪力墙试件。通过参数分析,研究了钢板厚度、竖向荷载和混凝土强度对双钢板混凝土组合剪力墙试件面外抗震性能的影响。试验结果发现:双钢板混凝土组合剪力墙试件具有良好的承载力和抗侧刚度,但比钢筋混凝土剪力墙在破坏阶段的延性要差。钢板厚度和竖向荷载都对双钢板混凝土组合剪力墙试件的面外抗震性能有较大影响,而混凝土强度对其影响不明显。利用ABAQUS有限元软件对双钢板混凝土组合剪力墙面外荷载试验进行了模拟,试件极限荷载的模拟结果和试验结果比较吻合。在试验和数值分析的基础上提出了双钢板混凝土组合剪力墙面外受弯承载力的计算公式,为核电工程双钢板混凝土组合剪力墙的设计提供参考。
[Abstract]:In order to study the seismic behavior of double-plate concrete composite shear wall under out-of-plane load in nuclear power project. In this paper, the low cycle reciprocating load tests on 6 shear wall specimens are carried out. The specimens are made of 5 double steel plate concrete composite shear wall specimens and 1 reinforced concrete shear wall specimen. The thickness of steel plate is studied. The influence of vertical load and concrete strength on the out-of-plane seismic behavior of double-plate concrete composite shear wall specimens. The test results show that the double-plate concrete composite shear wall specimens have good bearing capacity and lateral stiffness. However, the ductility of reinforced concrete shear wall is worse than that of reinforced concrete shear wall at the failure stage. The thickness of steel plate and vertical load have great influence on the out-of-plane seismic behavior of double-plate concrete composite shear wall. But the concrete strength has no obvious influence on it. The ABAQUS finite element software is used to simulate the external load test of double-plate concrete composite shear wall. The simulation results of the ultimate loads of the specimens are in good agreement with the experimental results. Based on the test and numerical analysis, a formula for calculating the external flexural bearing capacity of double-plate concrete composite shear walls is proposed. It provides a reference for the design of double steel plate concrete composite shear wall.
