천정 구조물용 트러스 시스템의 연결부 실험 및 내력 평가

General truss systems use the welded joints for the connections. The welded joints have weak points like construction error and difficulty of constructability. Therefore, this study develops the truss system for roof structure using bolted connections in the various joints. Also, we perform the several experiments for the safety evaluation of joint connections and evaluate the results for the security of bearing capacity of truss system.
