|Publication Date:||1 September 2011|
Scope and overview
This guide provides basic knowledge about posttensioning design and construction within the scope outlined in the following and is primarily intended for design professionals but can also be used by others involved with the design and construction of post-tensioned concrete buildings.
The scope of this document is limited to different kinds of post-tensioned concrete buildings, including parking structures that are designed in accordance with ACI 318, "Building Code Requirements for Structural Concrete and Commentary" (ACI Committee 318 2008). Although some aspects may be applicable to bonded post-tensioning, this document focuses on design and construction with singlestrand unbonded post-tensioning.
Chapter 2 provides an overview of typical post-tensioned floor
systems, types of available post-tensioning systems, and durability
considerations. Chapters 3 and 4 address the specifics of one-way
beam and slab systems and two-way slab systems. Chapter 5 provides
important information regarding proper design and detailing to
minimize effects of restraint-to-shorten
