Shear Strength of Precast Reinforced SHCC Walls

프리캐스트 SHCC 벽판의 전단강도

In this paper, direct tensile strength, $f_t$, and FR index, $F_i$, were considered, and factor ${\alpha}$ between and $f_t$ and $\sqrt{f'_c}$ was estimated through the results of preceding studies on the material properties of SHCCs in order to propose equation for evaluating shear strength of SHCC walls. Shear strength calculated by the proposed equation predicted shear strength of SHCC walls accurately, showing similar tendencies to experimental results.

본 연구는 SHCC 벽판의 전단강도 평가식을 제안하기 위하여 SHCC 재료의 직접인장강도($f_t$)와 섬유보강지표(FR index, $F_i$)를 전단강도식에 적용하였으며, 제안식은 SHCC의 전단강도를 예측하는 데 에 적절한 것으로 평가되었다.
