Abstract

The Japanese seismic design code allows for formation of plastic hinges at beam ends during large earthquakes. However, in cases in which seismic motion exceeds anticipated levels, seismic energy surpassing the structure’s absorption capacity may result in partial destruction, ultimately leading to the collapse of the whole building. Unexpected damage to buildings may also occur if they are subjected to long-period ground motions. To prevent such damage, we propose a displacement control device with hardening-type hysteresis. We performed experiments and analysis to verify the performance.
