This paper introduces a simplified nonlinear static seismic analysis method that consists of a simplified procedure for push-over analysis and a procedure modified from the capacity spectrum method from ATC-40. The simplified pushover curve is obtained on the basis of assumptions for failing behavior, such Abstract: strong-beam-weak-column behavior, which is commonly observed in low-rise reinforced-concrete buildings. This limits the usage of the method but allows other merits in analysis, such as abbreviating the calculation and allowing for strength degradation or detailed consideration for the capacity curve of members. Data of 31 school buildings from a damage databank were employed to validate the method. The analytical seismic capacity was compared to the earthquake intensity that each building experienced. The proposed method produced generally conservative results with no overestimates for the seismic capacity of the buildings.
