Abstract: A method for predicting the torsional strength of a reinforced concrete beam containing a rectangular opening is developed using the principles of limit analysis. A simple yield criterion for yielding under combined bending ...

Abstract: This paper presents the development of an analytical model for predicting the torsional strength of reinforced concrete beams containing a rectangular opening. The method is based on the collapse load analysis. Both upper ...

Abstract: An experimental investigation to study reinforced concrete beams with large rectangular openings under pure torsion is reported. The beams were rectangular in cross section. Beam dimensions, and the amount and arrangement ...
