What is post tensioning

Disadvantages of Post tension slab: The Post tension slab can be made only by skilful professionals. The slab has to carry a distributed permanent action of 1. The design procedure set forth in that publication had at that time been in use by the author for about 15 years. Appendix 6—Design examples for steel FRC slabs-on-ground using yield line method, p. Analysis to determine the maximum moments, thrusts and shears for design Design of sections and reinforcement arrangements for slabs, beams, columns and walls using the results from 3 Production of arrangement and detail drawings and bar schedules This structural design process has been carried out under use of BS design code of practice. The width of supporting wall is mm. The slab is mm thick and columns are mm square.

Post-tensioned PT slabs are typically flat slabs, band beam and slabs or ribbed slabs. PT slabs offer the thinnest slab type, as concrete is worked to its strengths, mostly being kept in compression. Longer spans can be achieved due to prestress, which can also be used to counteract deflections. Post-tensioned slabs use high-strength tensioned steel strands to compress the slabs, keeping the majority of the concrete in compression. This gives a very efficient structure which minimises material usages and decreases the economic span range when compared to reinforced concrete.

Post-tensioned slabs-on-ground provide a cost-efficient, high-performance solution for problems associated with ground-supported residential foundations on shrink-swell soils. The compressive stresses resist the anticipated tension stresses induced by the soil movements, enhancing the performance over a non-prestressed foundation. Cost benefits are achieved by reductions in quantities of concrete, steel and excavations, which in turn reduce labor costs. In less expansive soils, a uniform thickness foundation is utilized. Typical thickness ranges from 7. With the elimination of stiffening ribs, a post-tensioned foundation can be constructed rapidly eliminating labor and equipment to dig the ribs and dispose of excavations.

Post-tensioning is a method of applying compression after pouring concrete. Galvanised duct which is profiled using bar chairs follows the area where otherwise tension would occur in the concrete element. Steel strand Once the concrete has achieved required strength, the tendons are stressed by hydraulic jacks.

Slab design pdf

Post-tensioning, which is a form of prestressing, has several advantages over standard reinforcing steel rebars :. Post-tensioning, or PT, has become increasingly popular over the past 30 years or so as the technology has been perfected. At one time there were problems with corrosion of the cables, especially in deicing-salt-laden parking structures, but better materials and construction methods plus good training and certification programs have eliminated most problems. External post-tensioning is a good method for strengthening or retrofitting concrete structures. The applications for post-tensioning are almost endless, but what holds it back is the lack of experience among designers and builders.

Chandradhara Professor of Civil Engineering S. Slabs are used to provide flat or useful surfaces. A proper design of slab may have given a safe design.
