Abstract
Recent developments by the authors using non-linear optimisation techniques to find the critical collapse mechanisms for yield line analysis are described and the results are compared with those obtained by others in previously published work. A series of tests to compare various collapse load predictions, using yield line methods, with experimental data is described. It is shown that the authors' method improves the likelihood of finding the critical collapse mechanism for a slab, provides a realistic value for the ultimate load and allows the effects of changing the values of the yield moments to be investigated easily.
