Theoretical and Experimental Study of Shear Strength of Concrete Circular Sections Using Steel Hoops

콘크리트 원형단면의 횡보강근에 의한 전단강도 평가 이론 및 실험

The state-of-the-practice design expressions currently used for the calculation of shear strength of concrete columns due to circular transverse hoop steel were reviewed. From this, it was found that the single valued constant effective section area of shear steel to be conservative in some degree that concrete sections built in non-seismic regions. A general expression as n alternative was suggested considering the wide range of section configurations. The theoretical prediction was validated through the experimental observations.
