Ever since doctors told six-year-old James Berry Craddock that he'd never walk again, he hasn't let anything stop him. He not only walked again, he played every sport and activity that came his way. He played baseball. He swam. He skied. He golfed. He hunted. He fished. He used his can-do determination to build a successful development company--and to recover from bankruptcy when the real-estate climate changed. Moreover, he refused to let his business success get in the way of time with family and friends.
It is essential that sufficient satisfactory data should be available before any type of steel is used for prestressing . 2.2 Strength of prestressing steel The practice of specifying a minimum strength for prestressing steel has been ...
In reinforced or prestressed concrete construction, therefore, it is not practicable to specify that the concrete should have a certain precise cube strength, or that the reinforcement should have a particular yield stress or proof ...

The revised edition of this hallmark text is updated with the recent developments in design, construction and maintenance of Prestressed Concrete Structures.
The ultimate strength of PSC beam mainly depends on the strength of concrete and steel. In case of PSC beams, the concrete requires early compressive strength, and the steel should have higher tensile strength. The important feature is ...

This book was written with a dual purpose, as a reference book for practicing engineers and as a textbook for students of prestressed concrete.
The design of pretensioned concrete girders requires accurate estimates of prestress losses. These losses are affected by factors such as mix design, curing, concrete strength, and service exposure conditions.
