ABSTRACT

It was shown in Chapter 1 that structures can loose their stability in different ways: the equilibrium paths may have limit or bifurcation points. The bifurcation might be symmetric or asymmetric. The secondary equilibrium path might be stable, unstable or indifferent. Analysing the different types of the loss of stability the following questions arise:

- Are there also other types? - If there are some, how many and which types? - Which types do arise very often and which rarely? - How stable are these results? Does changing our mathematical model change the type

of the loss of stability or not?
