This report presents a consolidated treatment of initial and time-dependent deflection of reinforced and prestressed concrete elements such as simple and continuous beams and one-way and two-way slab systems. It presents the state of the art in practice on deflection as well as analytical methods for computer use in deflection evaluation.
The introductory chapter and four main chapters are relatively independent in content. One or two detailed computational examples for evaluation the deflection of beams and two-way action slabs and plates are given at the end of Chapters 2, 3 and 4. These computations are in accordance with the current ACI or PCI accepted methods of design for deflection.
Includes new Appendix B which presents a general method of recalculating the strain distribution at a section considering the effects of a normal force and a moment caused by applied loads, prestressing forces, creep and shrinkage of concrete, and relaxation of prestressing steel.
