The purpose of this study is to estimate the seismic performance assessments of elementary school buildings which constructed using 1980’s standard codes. The structural system of the considered school buildings has Reinforced Concrete(RC) moment frames with masonry walls. These school buildings were expected a poor performance for lateral force like earthquake forces because of masonry walls, specially partially masonry infilled (PMI) walls, that caused short-column effect, and need to be evaluated carefully. In this study, both Response Spectrum Analysis(RSA) without considering masonry walls and Linear Dynamic Procedure(LDP) Seismic Performance Evaluation with masonry walls were conducted. The results are as follows: By the analysis of RSA, Relative story displacements for all stories were satisfied but structural members like beams and columns didn't satisfied demanded performance criteria. However, results from the Tier.1 Seismic Performance Evaluation indicate that almost beams satisfied required performance criteria such as ‘IO (Immediate Occupancy Level)’ excepted G2 beams which seriously affected by torsion. From the results of RSA and Tier.1 Seismic Performance Evaluation, it is know that all columns of the investigated buildings needed to be strengthening about shear resistance due to the short-column effect.
