Abstract

본 논문에서는 유공형 강판의 횡방향 보강간격에 따른 넓은 보의 전단성능을 실험적으로 평가하기 위하여 횡방향 전단보강 간격과 넓은 보의 유효깊이를 변수로 고려하였다. 시험체는 총 8개로 유공형 강판으로 전단보강한 시험체가 5개, 무보강 시험체가 3개이다. 균열 및 파괴유형, 변형률과 하중-변위 곡선을 분석하였다. 유공형 전단보강재의 전단강도 기여분을 분석하고, 횡방향 전단보강의 최대간격을 제안하였다. 횡방향 전단보강 개수가 2개인 시험체에 비해 3개인 시험체에서 전단강도가 크게 나타났으며 유효깊이가 증가할수록 전단강도가 크게 나타났다.

In this paper, transverse shear spacing and effective depth of wide beams were considered as parameters to evaluate the shear capacity of wide beam according to transverse spacing of steel plates with openings in experimental way. The eight specimens were composed of: five specimens of shear reinforced by steel plates with openings and three non-reinforced specimens. Crack, failure mode, strain and load-displacement curve of specimens were analysed. Shear contribution of shear reinforcement is evaluated and maximum transverse spacing of shear reinforcement was proposed. Shear strength of the specimen that reinforced with three stirrup legs was higher than shear strength of the specimen that reinforced with two stirrup legs. And as the effective depth increased, shear strength was increased.
