| Abstract |
The purpose of this experimental study is to investigate the curling influence on structural behavior of single shear bolted connection of thin-walled carbon steel fabricated with four bolts. The end distance parallel to the loading direction is considered as main variables. The curling also occurred in this carbon steel connections with a long end distance and edge distance as the previous research regarding cold-formed stainless steel bolted connections. Furthermore, the ultimate strength and failure mechanism of test results were compared with those of current design standards such as AIK, AISC, AIJ, NAS and EC3. It is known that all specimens failed by block shear fracture, the curling led to the ultimate strength reduction of thin-walled carbon steel bolted connection and therefore design standards tended to overestimate the ultimate strength. |
