I. INTRODUCTION Under the assumption of linearity, four different seismic response analysis methods for two different reactor buildings were compared. This article describes some of the results of the comparison. The general method for calculating structural seismic responses is the square root sum of squares (SRSS) method. It is well known that this approach may result in a situation where the modes are close to each other.
