A simplified design procedure for load bearing brick masonry walls which considers eccentricity of wall loading and wall slenderness is presented. First, simplified wall bearing capacity equations and moment-rotation relations which reflect the effect of wall cracking are developed. Following this, a procedure for estimating the eccentricity of axial load in multi-story masonry structures is presented. Finally relations relating wall load eccentricity, wall slenderness and appropriate design stress reduction factors are given. The procedure is illustrated with a design example.
