- Abstract
- 본 연구의 목적은 박판 탄소강 일면전단 2행 2열 볼트접합부의 블록전단파단거동과 면외변형의 영향을 조사하는 것이다. 하중직각 방향 연단거리, 볼트직경, 피치, 게이지 치수를 고정하고 블록전단파단이 발생하도록 실험체를 계획한다. 접합평판의 두께, 하중방향연단거리를 주 요변수로 설정한다. 단순인장 실험을 실시하고 블록전단파단 양상, 최대내력을 현행의 설계기준식에 의한 예측치와 비교한다. 또한, 판 두께와 연 단거리에 따른 하중방향과 직각방향으로 발생하는 면외변형의 발생조건을 조사하고 면외변형의 발생으로 인한 내력저하정도를 고찰한다.
The purpose of this experimental study was to investigate the block shear fracture behavior and curling effect on
a single shear-bolted connection in thin-walled carbon steel fabricated with four bolts. The specimens that fail by block
shear were planned to have a constant dimension of the edge distance perpendicular to the loading direction, bolt diameter,
pitch, and gage. The main variables of the specimens were plate thickness and end distance parallel to the loading direction.
A monotonic tensile test was carried out for the bolted connections, and the ultimate behaviors, such as the fracture shape,
ultimate strength, and curling, were compared with those that had been predicted using the current design specifications.
The conditions of curling occurrence in terms of plate thickness and end distance were also investigated, and the strength
reduction due to curling was considered.
