The Concept of Dynamic Stabilityanalysis shows that there exists s bifurcation point and the postbucking branch corresponds to stable static equilibrium positions), there is no clear criterion of instability, although the criterion used for establishing critical conditions is very simple.

Two-Bar Simple Frames approaches discussed in Chapter 1. Moreover, if the support of the horizontal bar is movable along a vertical plane (Figure 6.1, model B), then the frame is imperfection sensitive for all loads. First the static analysis is presented and then the energy approach is employed for the estimation of cr

The Shallow Archn to introduce a different criterion for dynamic stability. The interested reader is also referred to the work of Lo and Masur and of Huang and Nachbar , who added the effect of initial geometric imperfections and viscoelastic behavior. More recently, stability boundaries (interaction c
