POST-TENSIONING IN BUILDING STRUCTURES . Ed Cross1. BE, ( ), MIEAust, CPEng SUMMARY. This paper outlines the major advantages of the use of POST-TENSIONING in BUILDING STRUCTURES . Economics of the POST-TENSIONING slab system are discussed including relative material contents, speed of construction, and factors affecting the cost of POST-TENSIONING . Various post -tensioned structural systems are presented, along with their relative advantages, applicability to various situations, and span to depth ratios to enable a designer to select the correct slab and beam thickness for a variety of situations. Finally, a discussion on the flexibility of post -tensioned BUILDING STRUCTURES in terms of future uses, new floor penetrations and demolition is presented.
6 The key factor in the speed of construction of a post-tensioned framed building is expedient use and re-use of formwork. Post-tensioning allows for the early recovery of formwork by early
