Abstarct: Flat slab systems are one of the most vulnerable structural systems that are susceptible to damage and collapse unless they are designed and detailed properly. The greatest disadvantage of those systems is the risk of brittle punching failure at the slab-column connection due to transfer of shear and unbalanced moment. The sudden and brittle nature of this phenomenon resulted in the progressive collapse of a number of buildings. Therefore there is a need to establish an effective, reliable and economical strengthening/upgrade method for them. Nowadays making use of FRP in strengthening is increasing because of their unique properties. In strengthening of slabs, FRP is using more often for flexural upgrade. But, use of FRP in the field of shear strengthening of slabs was paid attention fewer and was limited to few researches. This thesis will introduce shear upgrading schemes for slab-column connections using fiber reinforced polymers with ABAQUS finite element software. First to assurance from correctness of the numerical solution results, an experimental specimen was modeled in ABAQUS and the created analytical model was calibrated by experimental results.This examples in ABAQUS software a like quarter and dimensional (3D) was be modeling. After that you sure from accuracy modeling flow, the different states of setting FRP pages was be modeling and optimum state of that was got at the end of parametric ovservation on the example was get up, among ordinate, diameter, brand FRP pages was studied.
