Finite Element Model for Creep in Composite Masonry
A two-dimensional finite element model, developed to compute strains and stresses in composite masonry walls subjected to inplane external loads under linear elastic conditions, is extended: the influence of stress redistribution due to creep is included in the prediction of long-term creep strains. Two types of walls, a single wythe wall and a composite wall, are analyzed under various loading conditions to examine the effect of stress changes on the walls' creep behavior. A numerical technique for calculating creep strains and incorporating the effect of changes in stress is presented, and shown to lead to stable solutions. This technique is shown to account for the effect of stress changes on creep in masonry analyses. An investigation of the initiation of crack and eventual failure of the collar joint due to creep, shrinkage, and temperature strains is recommended.
