1) High rise buildings. In long span slab where beam is not provided & the slab of assembly hall, cinema theaters etc. like structure where the distance between columns are more, then post tensioning is used. It also used in construction of concrete slabs on the ground is areas where soil is more likely to move.
2) Stadiums: Post-tensioning allows long clear spans and a highly creative architectural approach.
3) Strengthening of existing structures that are susceptible to seismic shifts.
4) Long span bridges: - The use of post-tensioning for bridges where it allows very demanding geometry requirements, including complex curves, variable super elevation and significant grade changes.Precast concrete segment construction in bridges to allow for longer span by using post tensioned system.
5) Water tank: - Tanks and silos, post-tensioning can provide virtually crack-free concrete.
6) Wall panels
7) Parking decks , Tennis court
8) Slabs on ground: Post Tensioning is used extensively for slabs on grade where soils are likely to move (expansive soils)
