Abstract
The effectiveness of inner stirrups as the punching shear reinforcement forslab-column connections under eccentric loading was studied in this research withthe purpose of improving the punching behaviour. This research experimental dataand results study the effect of using steel, and glass fiber reinforced polymerstirrups (GFRPS) as punching shear reinforcement for interior slab-columnconnections (S-C-C) under eccentric loading. The experimental program consistsof six flat slabs with dimensions of 1600*1600 *150 mm, stub column having a200*200 mm cross-section with 700 mm total height extended outside both sidesof the slab. The variables were the materials used for manufacturing stirrups (Steel- GFRP), the distance between stirrups (50 or 70) mm, and the case of loading(eccentric or centric load). The experimental results showed a noticeable increasein punching shear resistance for the slabs reinforced with stirrups ranged from 28to 63% compared to the control specimen. Finite element analysis was performedusing the Abaqus/CAE6.14 software, and the results were compared to the
