| description | In this paper, numerical and experimental studies on the elastic behavior of glass fiber reinforced polymer (GFRP) with stiffeners in the GFRP section's web (to prevent local buckling) are presented. The GFRP profiles were connected to the concrete deck slab by shear connectors. Two full-scale simply supported composite beams (with and without stiffeners) were tested under impact load (three-point load) to assess its structural response. The results proved that the maximum impact force, maximum deflection, damping time, and damping ratio of the composite beam were affected by the GFRP stiffeners. The experimental results indicated that the damping ratio and deflection were diminished compared to hybrid beam without stiffeners by 16% and 22%, respectively, and increasing damping time by 26%. Finite element models were used to study pre-failure behavior. The numerical modeling results showed good agreement with experimental data in terms of loading path and final load. The damping ratio and midspan deflection values were greater than the experimental values by 6% and 12%, respectively. |
