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, research,
teamwork, and code development while advancing the quality, safety, efficiency,
profitability, and use of post-tensioning systems. Members of the Institute
include major post-tensioning materials fabricators in the U.S., Canada, and
Mexico, and manufacturers of prestressing materials in the U.S., Canada,
Mexico, Japan and Europe, and companies supplying materials, services and
equipment used in post-tensioned construction. In addition, PTI has more than
500 professional engineers, architects, and contractors.
One of PTIís principal functions is to provide technical
guidance on the design, construction, maintenance and repair/rehabilitation of
post-tensioned concrete structures. PTI has published over 30 informative
manuals and technical guides covering most aspects of post-tensioning. In
addition, PTI publishes a Technical Journal, newsletters, Technical Notes,
Frequently Asked Questions, and Technical Updates which give an in-depth
discussion and/or analysis of issues pertinent to designers in the
One of the goals of the Institute is to ensure
that specifiers and purchasers of post-tensioning materials receive products
and services which meet a recognized standard of quality. Working toward this
goal, PTI has established a certification programs both for manufacturing
plants and for field personnel. Current programs include:
Producing Unbonded Tendons
- Plants Producing Prestressed
Concrete (PC) Strand
1 Unbonded PT
Ė Field Installation
1&2 Unbonded PT Inspector
1&2 Unbonded PT Ironworker (Accelerated)
Installer Ė Stressor
1&2 Bonded PT Field Specialist
The Level 2 programs provide in-depth training and
complement the Level 1 course. The Level 1&2 courses are comprehensive
combined programs. Visit PTI certification page of
www.post-tensioning.org for more information on these programs. The
Certification Advisory Board (CAB) oversees four certification committees.
PTI sponsors an annual convention with technical sessions
and education seminars for design and construction professionals. In 2013,
over 40 seminars and certification workshops are planned. PTI's Education
Committee is also developing prototype college curriculums that can be used to
teach post-tensioning technology to engineers and architects.
PTI has 14 technical committees, including: Bonded Tendon;
Bridge; Cable-Stayed Bridge; Grouting; Rock & Soil Anchors; Unbonded
Tendon; Building Design; Repair, Rehabilitation and Strengthening;
Slab-on-Ground; Special Topics; Sustainability; Building Information Modeling;
Education; and Certification. The Technical Advisory Board (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 lead to a
new design procedure that is now the standard across the country.
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 decks.
A free exchange of idea on matters of mutual interest to the members is necessary for the success of all meetings. Indeed, such an exchange of views is essential to the successful operation of every trade association. However, certain areas of communication between competitors or between manufacturers and their suppliers and customers must be avoided, as posing potential antitrust problems.
PTI is committed to ensuring that its members comply with all applicable antitrust laws and regulations. To this end, PTI has adopted a Policy Statement on Compliance with Antitrust Laws that sets forth guidance for members in conjunction with all activities within the scope of, and related to, the official functions of PTI.
