摘要
本文应用有限单元法,对钢筋混凝土U 形薄梁稳定性进行了分析,给出完整的平面问题单元刚阵以及薄板弯曲单刚、稳定几何单刚;讨论了总刚形成及边界条件处理方法;并给出薄板稳定有限元源程序。
The article applies the finite element method,analyzing the steadycharacter of reinforced concrete thin-wall beam in U shape,giving out theelement rigidity matrix of plane problems,thin-slab bending and steadygeometry completely.It discusses the forming of general element rigidity andtreating method of boundary conditions,as well as the original program offinite element of thin-slab stability.
