Abstract

As the deep deck plate has the shape of open cross section, It can cause structural problems such as bending torsions due to instability of the section. There are a number of fasteners types which are frequently used on light gage steel diaphragms such as bolts, rivets, welds, and screws. In this study, the structural capacity of the self drilling screw connection between the deep deck and the reinforced cap plate was evaluated by experimental variables such as the arrangement method, numbers of screw, pitch of screw, and head plate thickness.

춤이 깊은 골형 데크는 그 단면의 형태가 개방형 단면(개단면(開斷面))으로 단면의 불안정성에 의한 휨비틀림 등의 구조적 문제를 일으킬 수 있다. 박판의 냉간성형강인 데크와 캡플레이트의 접합에 사용되는 연결재(파스너)는 볼트, 리벳, 용접 그리고 나사 접합이 있다. 이 연구는 냉간성형강을 사용한 춤이 깊은 데크와 보강용 캡플레이트간의 직결나사 접합부에 관한 실험적 연구로, 직결나사 접합부의 파괴거동과 최대내력에 영향을 주는 직결나사 배치방법, 직결나사 수, 직결나사 간격 그리고 직결나사 머리밑판의 두께변화를 실험변수로 하여 국외 설계기준식 비교 분석하고자 한다.
