초록
철근콘크리트 구조물의 전단거동은 수년간의 많은 연구에도 불구하고, 이론적으로 명확하게 규명하기에 어려운 문제중에 하나이다. 중공슬래브의 휨강도와 전단강도는 중공부로 인하여 감소되기 때문에, 이에 따른 구조물의 성능을 예측하는 것은 중요한 문제라 할 수 있다. 현재 각국의 중공슬래브 전단설계기준은 실험에 의한 기준식을 제시하고 있다. 따라서 본 연구에서는 철근비에 따른 일방향 중공슬래브 전단강도 산정방법에 관한 연구를 수행하기 위해 실험결과를 분석하고, 전단강도 산정식들을 비교, 분석하였다.
Abstract
The shear behavior of reinforced concrete structure is one of difficult problems that are not clearly identified theoreticallydespite the efforts of researchers for several years. Since bending and shear strength of hollow slab may decrease due to hollowpart inside slab, prediction of such structure performance is very important. Presently the formulas of shear designing standardexpressions of each country are formulas by experiment for hollow slab. In this study, the shear behavior of one-way hollow slabby reinforcement ratio were analyzed through experiment to conduct studying on estimation of shear strength, and then shearstrength formulas of hollow slab were compared and analyzed.
