The purpose of this study is to estimate the seismic performance of low-rise school building which constructed using 1980’s standard codes. The structural system of the considered school building is Reinforced Concrete(RC) Moment Frame with Full Masonry Infills(FMI) and Partial Masonry Infills(PMI). The masonry infills are usually not considered in structural analysis, but affect significantly the seismic performance of its structure. Many researches showed that real behavior of such buildings will vary during the earthquake events. It is generally agreed that an infilled frame structure performs better against earthquake forces, however, when a structure is only partially infilled, the phenomena is again different. By this analysis, four reinforced concrete frames with or without masonry infills were designed and tested under PUSHOVER analysis. Results shows that with Partial Masonry Infills(PMI), the columns become more shorter and get damaged prior to the other normal columns. The Full Masonry Infills(FMI) made an increase of both the initial stiffness and strength of its building.
