Why All The Stress About My Post-Tensioned Building? 

Post-tensioned (PT) concrete has been used as a building system since the 1950s and is commonly selected for its versatility and structural efficiency. As a result, a significant percentage of the U.S. building inventory utilizes post-tensioned horizontal concrete floor framing (i.e., slab-on-ground and elevated floors in buildings and parking structures). Many owners and operators are unaware that their asset contains post-tensioned concrete structural framing, and a limited number are aware of the fine nuances that make this framing system unique from a stewardship and engineering perspective.
In this webinar, engineers Timothy Gregor, Ralf Leistikow, and Tracy Naso explain what post-tensioning systems are, review indicators that these systems are not performing as intended, and describe various approaches to maintain and repair them. This webinar aims to educate building owners, operators, developers, and others about special attributes of post-tensioned structures that need to be considered during construction, maintenance, and modifications.
