전단 보강재의 폭 두께비에 따른 기초판의 뚫림전단 성능평가

다국어 초록 (Multilingual Abstract)

The shear behavior of foundation is evaluated the same as slab under the current building code (ACI318-11 and KCI 2012). But the shear behavior of foundation would be different from the behavior of slab received uniformly distributed load, because it changes according to the deformational pattern of the foundation plate and the distributional pattern of the bearing power of soil. Therefore, in case of the shear head reinforcement of foundation plate depth shall not exceed 70 times the web thickness and the flexural stiffness ratio shall not be less than 0.15. However, KBC 2009 does indicate that the depth-thickness ratio do not consider in case of steel buried in concrete due to the concrete to prevent buckling.
Therefore, this study shows the result of experimental investigation for the depth-thickness ratio of shear head reinforcement in foundation plate.
