Typical applications for strengthening concrete structures with FRP are listed below.

Buildings, car parks etc
Floor slabs to carry additional imposed loads or following structural alterations, such as forming new openings. Provide continuity over supports or between precast units.
Columns to carry additional load, increase seismic resistance or replace missing links.
Masonry walls to increase seismic resistance.

Road and rail bridges
Slabs to carry additional traffic loading, improve continuity or increase transverse bending capacity.
Edge beams following impact damage.
Columns to improve impact resistance or seismic performance.
Arched support structures.

Industrial buildings
Power station cooling towers to resist wind loading.
Towers, chimneys etc to increase seismic resistance.
Tunnels, lighthouses etc.
