강구조 인장 접합부의 블록전단 파단 = Block Shear Rupture of Tension Joint in Steel Structure

다국어 초록 (Multilingual Abstract)

The junction of tension materials, connected with high-strength bolt, should be designed to bear net section destruction, fastener fracture, and fracture of block shear considering yielding of the shear plane and the impact of shear retardation. Block shear among them means that tension side vertical and shear plane parallel to and shear plane horizontal in the direction of weight is torn in the form of "square piece;" it is a type of fracture well known in the junction such as simple beam or gasset plate connected with the bolts.
In other words, block shear is a situation of limitations where member resistance is determined by shear strength generated by the destruct line (DL) and tension strength generated by right-angled sections. Since the design law of limitation status of steel architecture was established in 1997, investigation into detailed block shear calculation formula is not thoroughgoing enough, and it is not put into practice very well.
This study showed that fracture shape and the proof stress of the fracture of 'ㄱ' steel (angle) are emphasized based on the previous results in order to find out feasibility of design criteria of nlock shear in terms of design law of limitation status and verify calculation formula of block shear.
