This paper reports the fact that an energy dissipation device (damage fuse) in its reinforced concrete (RC) frame can upgrade the ability to dissipate the energy created by earthquake excitations. When a damage fuse is applied to an RC frame, the fact that behavior such as cracking of attachment members and flexural yielding of reinforcing bars can reduce the effect of damage control should be taken into consideration, and the validity of performance evaluations of frames with a damage fuse and analysis models should be thoroughly examined in this light. Analysis models of RC frames with a damage fuse were found to effectively demonstrate the restoring force characteristics obtained from test results of horizontal loading. Several high-rise RC building projects have already chosen to use damage fuses to mini-mize serious damage to RC buildings subjected to strong earthquakes.
