Kompozitní FRP-HPC konstrukce pro mosty

Original language description

Fibre-reinforced polymers (FRP) are materials with comparable strength properties to steel but its weight varies from 1400-2500 kg/m3. FRP has high durability and low life-cycle costs and therefore it may compete with steel structural design in bridge structures. FRP has, however, one major disadvantage over steel and it is its low modulus of elasticity. In this study is described interaction between high performance concrete and handmade FRP plate. Creating composite action between FRP and concrete presents additional increase of stiffness of the composite element. The selection of FRP and HPC (high performance concrete) ensures great performance throughout the lifecycle of the structure placed in aggressive environment. Suitable properties of FRP may be increased by hand lay-up process for connection by perfobond rib shear connectors. Three push tests on FRP plates were performed to investigate behaviour of perfobond rib shear connectors.
