In plane finite element analysis of arches

摘要: A finite element procedure is described for the analysis of in plane behaviour frames composed curved or straight members. higher order quintic used to represent displacement fields, and its accuracy compared with that a cubic element. The virtual work equation obtain stiffness matrix load vector. These are then assembled form structure equations, which solved usual way. Structures slope discontinuities analysed by introducing transition at discontinuity. this investigated (a).
