Abstract
In this paper, we discussed the repair and the effect of decompression filling of epoxy adhesive of GLT beam-to-column drift pin joint. We applied same cyclic loading schedule to the joint before and after repair. As a result, strength and the absorption energy was the same or getting better compared with before and after repair. And after all loading programs was over, we dismantled the repaired joint. Therefore we confirmed the adhesive was able surely to be filled by the decompression technique. After the repair of this kind of epoxy, strength of joint has the possibility to go up more than it is built because three (bonding the crack, gap filling and the gluing members) were included in the effect of the repair.
