Title: Evaluation and Management of Tension Stiffening
Author(s): Richard H. Scott and Andrew W. Beeby
Publication: Special Publication
Appears on pages(s): 1-18
Keywords: codes; concrete; tension stiffening; deflection
Abstract:This paper discusses the importance of deflection control in reinforced concrete structures and highlights a number of problems which can complicate accurate deflection calculations. The tension stiffening phenomenon is then described in some detail followed by descriptions of the approaches used to accommodate it in major design codes. Recent experimental work which has resulted in new recommendations for the treatment of long term tension stiffening effects is summarised and areas of current research are indicated. Finally, the paper comments that the tension stiffening phenomenon, in view of its important influence on deflection control, is likely to remain a topic of considerable interest for the foreseeable future.
