Limit analysis of frames - Benchmarking and Applications
Keywords:
.Abstract
The analysis limit is currently experiencing developments and integrates increasingly into building codes. In this article, the methods of analysis limit of frames are exposed, particularly the equilibrium and the work methods. Then an application to a 2D frame is performed by the finite element program Plimit [1], the results obtained, i.e. the load limit that the structure can carry and the sequence of formation of plastic hinges, are discussed and compared to those obtained by commercial software (SAP 2000).The influence of the addition of the cross of St. Andrew on the limit load was studied. Finally, an example of a 3D frame is exposed.
