摘要
以复杂几何形状、边界条件及配筋形式的钢筋混凝土薄板为研究对象,根据钢筋混凝土有限元理论,以三角形分层组合式的弹性薄板弯曲单元为基础,研究了混凝土为各向异性材料在双向应力作用下的本构关系。
This paper analyzes the stress-strain relation of concrete as anisotropic material under effecting by two-way stress on the objects of reinforced concrete thin slabs with complex geometry,boundary condition and distributing of reinforce bars according to finite element theory of reinforced concrete,by using the triangle layered-assembled element of elastic thin slabs.
