In flat slabs, a brittle failure mode can rise due to poor transfer capacity of shearing force and unsymmetrical moment.
Existing of the opening around the vicinity of column increase the possibility of punching failure, in this case numerical analysis is necessary to understanding the structural behavior of such complex case.
This study presents nonlinear finite element analysis of the slab-column connections reinforced with GFRP bars by using the ANSYS15 software, in addition, the summary of experimental test result.
Solid 65 was used for modeling concrete element and GFRP bars were inputted by using link 180.
Link 10 was used to overcome the rigidity of supporting which gave a good rotation in the both sides.
For simplicity of analysis, only quarter-size have inputted.
Only discrete model have considered to modeling reinforcement bars.
Numerical result showed punching shear mode due to crashing of the concrete element before yielding the reinforcement bar.
The numerical results were compared with the experimental data which obtained from testing four interior slab-column connections and gave a good agreement.
Depending on the numerical and experimental result, existing of the openings reduced the punching shear capacity and increased the deflection of the specimens.
Increasing of the reinforcement ratio improved punching capacity.
Different stiffness have been observed between experimental and numerical model but have a liner behavior before first cracking
