It is of the advantages of high bearing capacity and economy for the gradient concrete beam with glass fiber reinforced plastic(GFRP) bars, so it will be applied widely in practical engineering. In order to acquire the short-term stiffness of simply-supported beams with gradient concrete and GFRP bars, 14 simply-supported beams were designed. Based on material constitutive model, finite element models of the beams are established by ABAQUS software. The stiffness variation law of the specimens is acquired. The simulation results are in good agreement with the experimental results, which proves the correctness of finite element modeling. Based on numerical simulation the stiffness calculation formula of the beams is provided, which can provide reference for the application of the beams in the actual engineering.
