This tutorial introduces the basics of prestressing, starting with the fundamental concept and industry technologies of pre-tensioning and post-tensioning. It relies on a first-principles approach in determining the state of internal stress from prestressing. It introduces the concepts of Decompression Moment, Cracking Moment, and reviews the evolving stress stages under increasing external loading. Simple examples are used to demonstrate the concepts.
This tutorial serves as a supplemental background to our more advanced courses on the conceptual bridge and seismic design.
