型钢混凝土T形短肢剪力墙非线性分析

Nonlinear Analysis of T-Shaped RC Steel Reinforced Concrete Short-Pier Shell Wall

为了研究型钢短肢剪力墙的承载力性能,运用大型有限元软件ANSYS设计了1∶1的型钢短肢墙试件。通过有限元软件的模拟试验,运用有限元软件的后处理功能处理的试验结果分析研究短肢剪力墙的承载力性能。分析了短肢剪力墙的破坏过程及破坏特征,对试件的极限承载力,屈服承载力,开裂荷载进行了深入的研究。定量地分析了短肢剪力墙的墙肢长宽比和型钢配钢量对其承载力的影响。在此基础上得到结论为:短肢剪力墙配置型钢后承载力提高较大,适当的型钢短肢墙的墙肢长宽比和型钢配钢量对其承载力有明显影响。

In order to investigate the beating capacity of the RC Steel Reinforced Concrete Short-Pier Shell Wall, the large-scale finite element software ANSYS is used to design 1 ： I steel short pier wall spec- imen. The performance of the beating capacity of short shear wall is analyzed and studied through the fi- nite element software simulation test and the results treated by the post-function of the finite element soft- ware. Short shear wall failure process and failure to yield bearing capacity, cracking load, ultimate bear- ing capacity of the specimen, are studied and analyzed in depth. The ratio between the length and width of wall pier of short shear wall and the effect of quantity of reinforced steel upon the carrying capacity are analyzed quantitatively. On the basis of which the conclusions are obtained ： the bearing capacity of steel reinforced short shear wall is greatly improved, the ratio between the length and width of wall pier of the appropriate steel reinforced short-pier wall and the quantity of reinforced steel will have the apparent effect upon their carrying capacity.
