Pushover analysis is base on shear building theory and there have two methods SERCB and TEASPA. Most of low buildings analysis is using TEASPA. However, TEASPA in brick wall analysis suggest that using equivalent diagonal strut simulation to make brick wall as the independent member and limit aspect ratio between 0.5 and 2 that lead the analysis often underestimate the strength that can’t simulate the destroy between the column and brick wall. This study was including the contribution of brick wall and unlimited by aspect ratio in analysis, so we don’t use diagonal strut simulation brick wall additional to use the concept of same displacement to superposition the capacity curve of column and brick wing wall as a combine column and substitution the model of nonlinear hinge in original column by TEASPA. The post shear strength analysis obviously higher 30 % than TEASPA. The lateral displacement at post strength and development of nonlinear hinge are close to the result in-site static pushover test in Kou-Ho. Despite the suggestion of this study were more complex, it is still a viable way.
