Abstract

 The effectiveness of inner stirrups as the punching shear reinforcement for
slab-column connections under eccentric loading was studied in this research with
the purpose of improving the punching behaviour. This research experimental data
and results study the effect of using steel, and glass fiber reinforced polymer
stirrups (GFRPS) as punching shear reinforcement for interior slab-column
connections (S-C-C) under eccentric loading. The experimental program consists
of six flat slabs with dimensions of 1600*1600 *150 mm, stub column having a
200*200 mm cross-section with 700 mm total height extended outside both sides
of 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 increase
in punching shear resistance for the slabs reinforced with stirrups ranged from 28
to 63% compared to the control specimen. Finite element analysis was performed
using the Abaqus/CAE6.14 software, and the results were compared to the  experimental results, which revealed a significant agreement. A Parametric analysis
was also performed on the validated model. Finally, Equations for punching
strength prediction were applied and then compared with the experimental results.
