Established in 1976, the Post-Tensioning Institute is recognized as the
world-wide authority on post-tensioning. PTI is dedicated to expanding
post-tensioning applications through marketing, education,
teamwork, and code development while advancing the quality, safety,
profitability, and use of post-tensioning systems. Members of the
include major post-tensioning materials fabricators in the U.S.,

(TAB) reviews and oversees all technical activities of the Institute.
PTI committees are open to all members and are instrumental in
providing guidance to practitioners and in advancing industry practices.
On occasion, PTI sponsors research to improve industry practices and to
advance the state-of-art. Although historically a small part of PTIís
programs, research is a growing and increasingly significant function.
For example, PTIís sponsored research on slab-on-ground foundations

PTI is committed to increasing the use of post-tensioning in a variety
of construction and repair applications. PTIís Marketing Committee has
developed a plan to increase usage in existing construction markets
and to develop new markets such as post-tensioned pavements and bridge
