Behaviour of Slab–Column Joint Under Lateral Cyclic Loading

Suganya, K. N. / Greeshma, S.

Punching shear failure is one of the main types of failure observed in the flat slab–column connections. In the present research work, numerical and experimental investigations were carried out to study the behaviour of exterior slab–column connection with various shear reinforcements in linear and critical patterns under lateral cyclic loading. Four types of specimens were analysed, conventional specimen (SC-NS), specimen with stud shear reinforcement in critical pattern (SC-SSRC), specimen with single-loop stirrups in linear pattern (SC-SLS) and specimen with closed-hoop stirrups in linear pattern (SC-CHS). The scaled model (1/4th scale) was tested under axial loading at the top of the column stub, and cyclic loading is given at the slab end. All the models with slab shear reinforcements (SC-SSRC, SC-SLS and SC-CHS) proved to be effective in resisting punching shear failure under axial and cyclic loading. The presence of shear reinforcements (SC-SSRC, SC-SLS and SC-CHS) significantly increased ductility compared to that of conventional specimen (SC-NS).
