A Coupling Effect of the Slab in Wall-Slab Structural Systems

벽체-슬래브 구조시스템에서의 슬래브의 커플링 효과

This paper is investigated the coupling effect in slab-wall structural system. An experimental investigation of reinforced concrete wall-slab structures were peformed. For the purpose of this study slab-wall substructures of an apartment building were chosen. And two specimens with different aid ratios have been tested. There were subjected to reserved cyclic loading, consistent with coupling action, with increasing imposed inelastic deformations. From. the result of this test, 1) in slabs, the coupling stress are not uniform across the width, 2) cracks are tending to be concentrated in the regions near the inner edges of the walls, 3) the effective width used in previous theoretical or model studies may not be enough.
