首先通过3个墙片的水平低周反复伪动力试验,对比研究了混凝土板墙加固后墙片与剪力墙的承载力、耗能能力等各项抗震性能。由于试验条件的限制,试验仅对比研究了120mm混凝土剪力墙与双面60mm混凝土板墙加固后墙片的抗震性能。在试验基础上,利用有限元软件建立合理的计算模型,将计算结果与试验结果进行了对比分析;利用该计算模型模拟了用不同厚度的混凝土板墙加固墙片和混凝土剪力墙,系统分析了混凝土板墙加固后墙片与剪力墙的极限承载力,分析了将加固后墙片看作抗震墙的可行性。通过有限元的分析,弥补了试件不足的缺陷,完善了研究方法。
Firstly, the horizontal low-cycle repeated pseudo-dynamic test of three walls was used to study the seismic performance of the bearing capacity and energy dissipation capacity of the wall and the shear wall after reinforced concrete wall. Due to the limitation of the test conditions, only the seismic performance of 120mm concrete shear wall and double-sided 60mm concrete slab wall reinforced wall was compared. On the basis of the experiment, a reasonable calculation model is established by using the finite element software, and the calculated results are compared with the test results. The calculation model is used to simulate the reinforcement of the wall slab and the concrete shear wall with concrete slabs of different thicknesses. The system analysis The ultimate bearing capacity of the wall and the shear wall strengthened by the concrete slab wall is analyzed. The feasibility of considering the reinforced wall as the anti-seismic wall is analyzed. Finite element analysis to make up for the shortcomings of the lack of test pieces, improve the research methods.
