Abstract


Application of GFRP composites in civil engineering is still not large but already noticeable. Advantages ofthis material, such as: low volume weight, relatively high stiffness and strength, well fatigue resistance, easiness inshaping, high material damping and high environmental resistance, make it attractive for bridge and in particular footbridgedesigners. It is estimated that nowadays in the world there are realized hundreds of bridges, the construction ofwhich, whole or in part is made of GFRP. Most of them are small span structures. However, it is possible to find someinteresting designs. The paper presents an overview of the most spectacular examples of footbridge structures, in whichthe GFRP materials plays a key role. The few examples are: Aberfeldy Footbridge in Scotland, the world's largeststructure of this kind; Lleida Pedestrian Bridge, the longest arch bridge made out standard GFRP pultruded profiles orEXPO Footbridge in Lisbon, truss bridge of 30 m span length. The last example is the footbridge designed and constructedby polish consortium Fobridge. The footbridge, which arose as a result of scientific project was studied in agreat details taking into account, among others: material testing, validation studies and load tests.
