Limit Analysis Of Anisotropic Or Jointed Media - Application To Unreinforced Masonry Shear Walls


A simplified numerical method for calculating the lower bound limit load in anisotropic media is presented, with particular emphasis on the in-plane behaviour of unreinforced masonry walls.  Results from this new technique  are compared to those of an earlier lower bound formulation by the same authors.  Both techniques are based on the limit  analysis of jointed rock but differ in the assumptions about  the material properties.  In the previous method, the masonry material is assumed to be anisotropic and inhomogeneous due to the presence of the discontinuous joint  sets in the masonry composite. The new, simpler technique, however, assumes homogeneous material properties.  An example is given to illustrate the accuracy of the new technique.  10 refs.
