型钢混凝土梁柱框支剪力墙结构抗震性能试验研究

框支剪力墙结构在实际工程中经常被采用,震害表明钢筋混凝土框支剪力墙结构抗震性能较差,本文提出型钢混凝土梁柱框支剪力墙结构对此加以改进。作者进行了4个1/4缩尺模型在竖向荷载和单调及低周反复水平荷载作用下的对比试验,其中3个试件采用型钢混凝土转换梁、型钢混凝土框支柱,1个试件采用钢筋混凝土转换梁、钢筋混凝土框支柱。我们分析其承载力、刚度、变形、延性和破坏形态等。试验结果表明,型钢混凝土梁柱框支剪力墙结构承载力高、延性好、滞回曲线丰满,变形能力和耗能能力较强。

Experimental study on seismic behaviors of shear wall supported by frame with steel reinforcing

The structure of frame-supported shear wall has been widely used in many cases.In order to improve the seismic behaviors of this type of structure with the frame normally in reinforced concrete,the frame with steel reinforcing is proposed in this paper.An experimental investigation was conducted to study the behaviors of the proposed structure subjected to the simulated seismic load.The tests exerting constant vertical load and monotonic or cyclic lateral load were carried out on four one-forth-scale specimens,three consisting of steel members encased in reinforced concrete frame supporting concrete shear wall.Load-bearing capacity,stiffness,deformation,ductility,and failure modes were discussed based on the test results.The results of the experiment indicate that the system of shear wall supported by frame reinforced with steel members possesses exceptional strength,ductility,and has better energy dissipation capability for earthquake-resistance.
