带边框柱中高剪力墙非线性有限元分析
|
摘要
在模型试验的基础上,采用ANSYS有限元分析程序,对钢筋混凝土带边框柱中高剪力墙模型结构在单向水平荷载作用下的力学性能进行了非线性有限元分析,从理论计算的角度进一步了解了这类结构在水平荷载作用下的开裂、变形及破坏全过程,并与试验结果进行了比较.结果表明,有限元分析结果与试验结果符合较好,设计合理、构造措施得当的带边框柱中高剪力墙具有良好的受力性能和变形性能.
Based on the model test,mechanical behavior of moderate R.C.shear wall with frame column is analyzed with ANSYS finite element program.The analyses include: the evolution of crack patterns,deformation and failure course of the specimens.The computing results agree so well with the experimental data that the finite element method can be validated to be suit to research mechanical properties of this kind of structures,and the results show that the seismic behavior of moderate R.C.shear wall with frame column is satisfied through rational design and related constructions.
