Abstract
This research aims to gain understanding of the effectiveness of a novel flat truss shaped punching shear reinforcement (FTSPSR) in enhancing the punching shear capacity of flat slab structure. The numerical analyses were performed using ANSYS Static Structure. The context of this study is the prevention of punching failure by the addition FTSPSR and the effect of varying the number of segments in the truss assembly. A total of four models were constructed for this study. The results showed that the presence of FTSPSR was able to reduce the maximum deflection in the range of 5.33–10.57%. In addition, model with 6 segments in the truss assembly performed better than the rest of the models. The ability of the novel FTSPSR to reduce the maximum deflection can be considered as a practical solution enhance the punching shear capacity and failure of flat slab structure.
