模网混凝土墙体抗剪承载力与延性分析

为了推进新型结构体系——建筑模网混凝土结构的应用,以有限元软件ANSYS作为研究工具,分别对普通混凝土剪力墙以及Ⅰ型、Ⅱ型模网混凝土墙体的抗剪性能进行了非线性有限元分析,对比了Ⅰ型、Ⅱ型模网混凝土墙体在抗剪承载力、延性等方面的特点,结果表明:模网混凝土墙体和普通混凝土剪力墙相比,两者的极限荷载相近,前者的开裂荷载大于后者,延性比后者稍差;Ⅱ型模网混凝土墙体在承载力和延性性能方面比Ⅰ型模网更优。

Analysis on shear strength and ductility of the concrete wall with permanent shuttering kit

In order to promote a new structural system, i. e., the concrete structures with permanent shuttering kit, nonlinear analysis on shear resistance capacity of general concrete shear wall and the concrete walls with permanent shuttering kit of type Ⅰ and type Ⅱ was given by ANSYS software. The characteristics of shear strength and ductility of the concrete walls with permanent shuttering kit of type Ⅰ and type Ⅱ were compared. The ultimate loads of the concrete walls with permanent shut-tering kit and general concrete shear wall were found to be similar, but their cracking loads and the ductility were different. The cracking load of the former was bigger than the latter while the ductility was contrary. The concrete wall with permanent shuttering kit of type Ⅱ has better shear resistance capacity and ductility than that of type Ⅰ.
