八元对称平面桁架结构的突破

一个对称的平面结构由八个相等的桁架构件组成,这些构件被嵌入到铰链支座中。 当结构发生弹跳时,通过集中力和在临界临界点上的节点变形施加荷载。 Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. 在这个例子中不考虑自重。 Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at the given deflections.
