Design of the hybrid FRP/concrete structures for bridge constructions

Abstract

The current paper deals with the analysis of the hybrid FRP/concrete structures for bridge constructions. The glass fiber composite structure connected with the reinforced concrete was analyzed numerically. The detailed analysis of the material properties was conducted and then used in the design process of the final construction. The different loading conditions were investigated taking into account nonlinear concrete material model. The preliminary parametric optimization was applied including the different distance between bridge supports and different support shapes. Besides, the influence of two different effects of the concrete shrinkage on the strength properties of the hybrid structure was verified.
