TORSIONAL STIFFNESS OF CONCRETE BEAMS UNDER COMBINED LOADING

Abhishek Sharma, G S Pandit

Open publisher page 0 citations

Abstract

The torsional stiffness of concrete beams in combined bending and torsion has been reported earlier by Pandit and Warwaruk. In this paper an experimental investigation involving 77 beams tested under axial compression, biaxial bending couples and torsion has been reported. Based on the experimental results, an empirical expression for the torsional stiffness for the more general load combination has been derived. The use of the equation has been explained with the help of an illustrative example. (Author/TRRL)
