FRP sandwich structures in bridge and building construction

Selected applications of fiber-reinforced polymer (FRP) sandwich structural elements in building and bridge construction are discussed. It is shown how in building construction this technology enables the integration of functions such as load-bearing capacity, thermal insulation, daylight entry and energy production, into single, large-scale and lightweight roof or façade panels. In bridge construction, the high resistance against environmental impact enables conceiving much simpler construction details because no sealing layer is required, and lightweight deck panels enable the widening of existing bridges without additionally loading the substructure.
