CFT를 적용한 강관 다이아그리드 접합부의 강도 평가

Nowadays, in several countries including China, highrise buildings using diagrid system with circular steel tube had been constructed and designs using diagrid system is in progress. In diagrid system, connection is very important node that transfer load to each other members. Connections are categorized 3 types(external diaphragm type, internal diaphragm type and through type). Each type of connection has different performance and constructbility. In this study, the compressive strength for the connection with cross-shaped plate in circular steel tube and the compressive strength for the connection adopted in circular steel tube(CFT connection) were evaluated by the experiment.
