PURPOSE AND SCOPE

The purpose of this course is to train field personnel involved in the installation, stressing, grouting, and inspection of grouted post-tensioning systems. The bulk of the course material will focus on multistrand post-tensioning; however, post-tensioned bar systems, which share many of the same procedures and characteristics, will also be discussed.

This course is applicable to the use of these post-tensioning systems in various types of structures, including bridges, buildings, ground anchors, slabs and storage tanks. This manual and the corresponding course have been developed specifically for these applications. Procedures applicable to single strand unbonded tendon systems are covered in other PTI documents and courses.
