混凝土板墙加固后墙片与剪力墙性能的对比研究

Comparative Study on Brick Wall Strengthened with Concrete Splint and Shear Wall

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。

Through a series of low-cycle repeated loads experiments,the paper does comparative studies on the seismic behavior of concrete shear wall and brick wall strengthened with concrete splint firstly.Because of the limitations of experiment,the study focuses on the 120 mm shear wall and brick wall with double 60 mm concrete splint.On the basis of the experimental study,we use the finite element software to establish a rational model.And then we use the models of the walls to expand the calculation about the wall strengthened with concrete splint.By analyzing the results,we get the conclusion about the wall＇s ultimate load when the wall has different thickness.Through the finite element analysis,we improve the research methods.
