Prestressed Concrete - an overview ScienceDirect Topics

R. Park, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 VI.A Introduction. Prestressed concrete is defined as concrete that has been prestressed so that the induced internal actions counteract the external loading to a desired degree. Prestressed concrete members can be placed in one of two categories: pretensioned or posttensioned.
