摘要

提出一种新型装配式钢筋密网抗侧力墙板结构形式。为研究此装配式钢筋密网抗侧力墙板的抗震性能，制作足尺寸试件，通过拟静力往复加载试验获得滞回曲线，并通过滞回曲线对该墙板的滞回特征、骨架曲线、刚度退化曲线、耗能能力进行分析研究。试验结果表明：该墙板在层间角1/250时承载能力未出现明显下降；与钢筋为斜杆式结构的装配式抗侧力墙板试验结果进行对比，钢筋为密网式结构的抗侧力墙板表现出更好的承载能力、抗震耗能能力和稳定性，极限承载力提高约5.5%，消耗的总能量值提高约11%。采用ABAQUS软件对装配式钢筋密网抗侧力墙板进行有限元分析，模拟结果与实验结果基本吻合，与装配式钢筋密网抗侧力格构柱进行有限元分析对比，装配式钢筋密网抗侧力墙板抗震耗能能力提升33%。

Abstract

A new type of prefabricated reinforced concrete wall panel is proposed. In order to study the seismic performance of the wall panel, full-size specimens were made, and the hysteretic curve was obtained by quasi-static reciprocating loading test. The hysteretic characteristics, skeleton curve, stiffness degradation curve and energy dissipation capacity of the wall panel were analyzed through the hysteretic curve. The test results show that: the bearing capacity of the wall panel does not decline significantly when the interlayer angle is 1 / 250; compared with the test results of the fabricated lateral load-resistant wall panel with inclined bar structure, the reinforced concrete reinforced concrete wall panel with dense mesh structure has better bearing capacity, seismic energy dissipation capacity and stability, the ultimate bearing capacity is increased by 5.5%, and the total energy consumption is increased by 11%. ABAQUS software is used to carry out the finite element analysis of the prefabricated steel dense mesh anti lateral force wallboard. The simulation results are basically consistent with the experimental results. The finite element analysis and comparison with the fabricated steel dense mesh anti lateral force lattice column show that the seismic energy consumption capacity of the fabricated steel dense mesh wall panel is increased by 33%.
