| Abstract: | This paper discusses the application of elastic flexure-resisting hings, a simplified model of pipe bend, in the structural analysis of piping systems. In order to reduce the number of elements and nodes of a piping system, the element stiffness matrix and the equivalent nods loads of straight pipe element with joint flexibility are formula ted, .The results obtained in this paper are in good agreement with those by using conventional pipe bend element of finite element method. |
