Abstract
The finite element simulation was performed for 8 carbon fiber reinforced plastic (CFRP) sheets reinforced steel-concrete composite beams via ABAQUS software, in an effort to further investigate their mechanical properties. Next, the influences of shear connection degree and elasticity modulus, width and constitutive relation of CFRP sheets on the mechanical properties of steel-concrete composite beams were studied. Subsequently, their load-dependent change laws of midspan deflection were reported in detail. The simulation results show that the reinforcement effect on the negative moment region of each composite beam is improved with the increase in the elasticity modulus, width of CFRP sheets and the shear connection degree.
