Abstract

The purpose of this paper was to investigate the block shear and the fracture in the net section, according to AISC Specifications, by analysing the shear lag effect in the block shear rupture of the single angle with three or four bolt connection. Specimen with three or four bolt connections showed that failure generally went from block shear with some net section failures to classic net section failures. From the test results, showed that the connection length, the thickness of angle, and reduction factor, which affect the block shear rupture, were investigated. According to the test results, it is suggested that the calculation of the net section rupture capacity by using the reduction factor of U, that was suggested by Kulak, is needed.

본 연구는 볼트개수 3개 또는 4개로 접합된 인장력을 받는 ㄱ형강의 블록전단 파단시, 전단지체 효과를 분석하여 AISC의 블록전단식과 순단면파단식을 비교 검토하였다. 볼트 3개 또는 4개로 접합된 실험체의 경우 순단면 파단과 같은 블록전단, 순단면 형태의 파단으로 파단되었다. 실험결과는 블록전단에 영향을 미치는 접합길이, 실험체의 두께, 감소계수 등을 변수로 분석하였다. 실험결과에 따라, 블록전단내력 산정시 Kulak의 제안한 감소계수 U를 계산해서 적용하는 것이 필요한 것으로 판단된다.
