Three-dimensional limit analysis of rigid blocks assemblages. Part II : load-path following solution procedure and validation

摘要

A novel solution procedure for the non-associated limit analysis of rigid blocks assemblages is proposed. This proposalproduces better solutions than previously proposed procedures and it is also able to provide an insight into the structural behaviour prior to failure. The limit analysis model proposed in Part I of this paper and the solution procedure are validated through illustrative examples in three-dimensional masonry piers and walls. The use of limit analysis for three-dimensional problems incorporating non-associated flow rules and a coupled yield surface is novel in theliterature.
