The strength of the column bases was changed at 15 steel frames that are fabricated according to the Japanese seismic design code. Numerical analyses regarding the seismic response of these frames were carried out, applying a variety of ground motions. The maximum plastic rotation, maximum increment of plastic rotation during half the vibration cycle, and cumulative plastic rotation are considered to be the parameters that represent the magnitude of plastic deformation. As a result, the cumulative plastic rotation divided by the maximum increment of the plastic rotation during half the vibration cycle of the column base increases rapidly as the strength of the column base decreases. However, for the second-floor beam ends, these values are almost constant even if the strength of the column base decreases.
