带钢筋的四节点板单元刚度矩阵初探

Research of element stiffness matrix of the four-node plate with reinforce element

充分考虑了钢筋混凝土板中钢筋实际发挥的抗弯作用,将钢筋混凝土中的钢筋作为平面梁单元,既考虑了钢筋的轴向作用,也考虑了钢筋的横向作用、抗弯作用,推导得到了钢筋钢筋混凝土板中钢筋对板单元的贡献矩阵,得到了钢筋混凝土四节点板单元的刚度矩阵。

In this paper, the real function of the reinforcement is fully considered. The reinforcement is discussed as planar beam element,its axial and resistance bent function are all included. Contribution of stiffness matrix of the reinforcement on the four-node reinforced concrete plate element is deduced.
