摘要：

In this paper, an application of rigid block limit analysis to confined masonry shear walls is presented. A simplified micro-modelling approach is adopted, based on the discretization of the single masonry unit into two blocks separated by cohesive contacts. Failure modes, which may occur at joint interfaces as well as in the masonry unit itself, involve crushing, cracking and sliding. An iterative solution procedure of linear programming problems was used to take into account non-associative flow rule as well as brittle behaviour of cohesive joints in cracking failure. To show the accuracy of the proposed modelling approach, a case study from the literature of a confined masonry panel is analysed. The obtained results are compared with experimental tests and with the outcomes of other modelling approaches used in the literature.
