Abstract:
Various methods for predicting the strength of slab-column connections that transfer shear force and moment have been proposed, but in all those methods, calculated values are conservative when compared to the measured strengths. That conservatism is due to an underestimation of the moment which is transferred between the slab and the column by torsion. Torsion tests of slab-column connections were carried out to directly investigate the magnitude of the moment that can be transferred by torsion. In this paper, those tests are described and a method for predicting the strength of slab-column connections transferring shear and moment is proposed which compares well to available test data.
