Fibre reinforced polymer (FRP) composites have become known for their specific advantages for civil infrastructure construction. High corrosion resistance in particular is one such strength, which has led to successful applications worldwide. This paper focuses on the structural applications of FRP composites as major load-carrying members (therefore strengthening of existing structures is not included) in aggressive environments. It is review and comparatively studied for environmental effects on FRP composites at the structural level mainly about joints and connections, including elevated environmental temperatures, humidity and water immersion, and ultraviolet (UV) exposure. The quantifications of such environmental effects on structural responses further assist development of large scale civil structures made from FRP composites. We therefore also present a few implementations of FRP composites in civil infrastructure construction including i) FRP truss and frame structures in high humility areas, ii) FRP composite bumper systems for bridge piers, iii) floating FRP structures for solar panels, iv) FRP steel composite piles for foundation applications, and v) FRP sheets, planks and piles for modular assembly of a retaining wall. These results are introduced as initiatives from own experiences, with the aim of demonstrating their applicability and providing examples for others with similar needs.
