- Abstract
- The finite element method is used to investigate the behavior of composite masonry walls subjected to vertical and horizontal in-plane loads, and due to creep strains and temperature variations. A solution procedure using two-dimensional plane strain finite elements is proposed to compute correct stresses in the collar joints of composite masonry walls. An improved failure criterion for the block wythe-collar joint interface is proposed and a failure analysis procedure is presented. Failure loads in composite masonry walls of various heights using the proposed failure criterion and method of analysis are determined.
