| 摘 要： | 综述了曲梁单元的发展.指出曲梁单元的非线性分析方面尚处于混乱阶段,而且有些学者认为直梁单元不能用于曲梁的非线性分析.通过三个实例表明了不同的曲梁理论对不同的结构、不同的受力条件,都有不同的适用性.最后通过编制的直梁单元的几何非线性程序,证明了直梁单元完全可以用于曲梁的非线性分析.

| Abstract: | In this paper, progress on curved beam elements is summarized. Research work on the nonlinear analysis of the curved beam elements is faced with a very confusing situation, and some previous researchers make an argument that straight beam elements can not be used to study the nonlinear analysis of curved beams. According to three examples, it is made clear that each curved beam theory has its own applicability. At last, by a computer program of geometric nonlinear analysis of the frame structures using straight beam element, it is proved that the straight beam elements can be used in the nonlinear analysis of curved beam structures. |
