Finite Element Model to Compute Stresses in Composite Masonry Due to Creep, Shrinkage, and Temperature

S. C. Anand / A. Gandhi / R. H. Brown

A two-dimensional finite element model is developed to incorporate the effects of creep, moisture, and thermal strains in the wythes of composite masonry walls. A numerical technique is presented to apply joint load increments on a wall that are equivalent to the creep strains for a given time element. The proposed technique is shown to lead to stable solutions. A similar scheme is also used to compute strains and stresses due to thermal and moisture strains. It is found that substantial stress redistribution occurs in a composite wall due to creep and that the effects of thermal and moisture strains cannot be neglected.
