When heavy superimposed loads are encountered in building construction such as in subterranean structures carrying earth loads, long span transfer girders, or heavily loaded pool slabs, "bonded" post-tensioning can be used in lieu of unbonded in order to reduce the amount of non-prestressed reinforcement that is required to satisfy code requirements for ultimate strength. In this application of post-tensioning, the strand is not coated or extruded in a plastic sheathing and multiple strands are housed in large diameter ducts that are installed prior to the placement of the concrete. Since multiple strands are placed inside one common duct, they must all be stressed simultaneously requiring the use of a large stressing jack. Once the tendons are stressed and anchored, the duct is filled with a non-corrosive grout that effectively bonds the strands to the duct and to the concrete member. Bonded post-tension systems are most commonly used in bridges, and in conjunction with heavy transient live loads. Suncoast has the capability of supplying bonded slab tendons that are housed in flat ducts of up to 140 kip working force each, or beam tendons housed in round ducts of up to 1,200 kip working force each.
