Title: CRC 80 REEXAMINATION OF PUNCHING SHEAR STRENGTH AND DEFORMATION CAPACITY OF CORNER SLAB-COLUMN CONNECTION

Abstract:Effects of slab flexural reinforcement on the punching shear strength and deformation capacity of corner slab-column connections without shear reinforcement are evaluated in this study. Six isolated corner slab-column subassemblages were tested under combined gravity-type loading and lateral displacement reversals. Results from present and previous studies indicate that punching shear strength and deformation capacity per ACI 318-14 is not conservative for corner slab-column connections. For connections subjected to gravity-type loads only, a shear strength model considering effects of the equivalent slab top flexural reinforcement ratio and
the critical section aspect ratio (bo/d) is proposed. For connections subjected to combined gravity-type loads and lateral displacement reversals, the gravity shear ratio determined based on the proposed model improves applicability of the shear decay model per ACI 318-14.
