摘要
针对异形柱在框架中的受力特点 ,结合杆系结构有限元素法中杆件几何物理参数的要求 ,提出了新的异形柱等效原则 ,较好地解决了当前通用高层电算软件难以较准确分析异形柱框架的问题 。
In this paper, according to mechanics characteristic of special-shaped R.C columns in frame structure, and considering the nature of geometric and physical parameters of bars in finite element method in bar system structure, the new equivalent principle of special-shaped R.C columns is put forward, which not only solve the problem of the framed structures with special-shaped R.C columns which can not be accurately analyzed by the general software for tall building, but also lay the foundation for widely applying the special-shaped R.C columns.
