철골연결재 및 고인성섬유복합체를 이용한 프리캐스트 보-기둥 접합부의 개발

초록

In this study, new moment-resisting PC beam-column joint was made upof hybrid steel concrete. It has square hollow tubular section in concrete column and connecting plat in precast U-beam. And we use the ECC. An experimetal study was carried out to investugate the joints were cast-in-situ concrete area and transverse reinforcement within the loint. Based on the test results, we observed main differences of structural behavior because of different bonding characteristics between steel, concrete and ECC. This connection detail is able to induce the plastic hinge out of the ECC and steel plate.
