A STUDY ON SEISMIC GROUND MOTION INTENSITY TO ESTIMATE THE DAMAGE RATES OF LOW- AND MIDDLE-RISE REINFORCED CONCRETE BUILDINGS IN THE SHIKOKU REGION

This study investigated seismic ground motion intensity to estimate the damage rates of low- and middle-rise RC buildings due to various earthquakes. It calculated the vulnerability functions of analytical models of RC buildings for earthquake motions with different spectral characteristics and evaluated the effects of earthquake motions with different spectral characteristics on vulnerability functions. The results confirmed that the average acceleration response spectrum of the periodic band corresponding to the primary natural period of the building can usually estimate the damage rates of low- and middle-rise RC buildings due to various earthquakes.
