Guidelines for the Design of Post-Tensioned Floors

POST-TENSIONING SYSTEMS In the U.S. and Canada, post-tensioned buildings and parking garages are typically constructed with seven-wire, 0.5-in.-diameter (12.7 mm), unbonded single-strand (monostrand) tendons. These tendons, with a typical strength of 270 ksi (1860 MPa), are also greased and sheathed. One reason for the widespread use of the

General Overview of Post-Tensioned Concrete Design

In simple span beams the primary post-tensioning (P/T) moments induced by the prestressing force are directly proportional to the eccentricity of the tendons with respect to the neutral axis of the member (i.e. Pe). In continuous or indeterminate post-tensioned structures the moments due to the prestressing
