摘要：

A variational methodology for investigating the dynamic stability of frames subjected to a suddenly applied load of constant magnitude and infinite duration is developed and successfully demonstrated through a simple two‐bar frame. A criterion for dynamic stability is presented on the basis of which dynamic snap‐through loads are established. Using Timoshenko's beam theory the individual and coupling effects of various parameters (i.e. cross‐sectional shape, loading eccentricity, slenderness ratio and moment of inertia ratio of the two bars) on the dynamic and static snap‐through load are fully assessed.
