Abstract
In this study, specimens of rigid frame joint were produced by integrating joints with adhesive and other specimens were produced by inserting a wooden gusset integrated with a column member into a slit-processed beam member and joining them with pins. Then the moment resistance performances of the specimens were examined. For the wooden gusset, a GFRP-reinforced wooden gusset was used. The calculation results of perfect elasto-plasticity for the frame specimens for which a GFRP-reinforced wooden gusset was inserted into and joined with the slit-processed beam member by pins were 20-80% lower compared to the control group which consisted of steel plate-inserted frame specimens. The rigid frame specimens for which the column and beam members have been integrated with adhesive showed almost no initial residual transformations, as well as 38% greater initial rigidity and 41% greater plasticity compared to the steel plate-inserted joint.
본 연구에서는 접합부가 접착제로 일체화된 강절형 기둥-보 접합 시험편과 슬릿 가공한 보부재에 기둥부재와 일체화된 목질접합물을 삽입하고 핀으로 접합한 시험편을 제작하여 모멘트 저항성능을 검토하였다. 목질접합물은 GFRP로 보강한 적층판을 제작하여 사용하였다. 슬릿 가공된 보부재에 GFRP보강적층판을 삽입하고 핀으로 접합된 기둥-보 시험편들은 완전탄소성 모델 분석으로 산출된 특성치들이 대조군인 강판삽입형 기둥-보 시험편보다 20~80% 낮게 측정 되었다. 기둥부재와 보부재가 접착제로 일체화된 강절형 기둥-보 시험편은 초기잔류변형이 거의 관찰되지 않았으며, 강판 삽입형 접합부보다 38% 향상된 초기강성과 41% 향상된 소성률이 측정되었다.
