Dr. D. A. Greenwood: ‘I should like to say how much I appreciate this paper by Mr. horburn-who is a former competitor of mine-and Mr. Macvicar. It is very interesting and informative. They have clearly a very impressive record of completed structures behind them, as is evident by the slides which they have shown, indicating many different buildings.‘
In order to simplify the calculation of the ultimate bending capacity of rectangular, solid, or hollow, reinforced concrete beams subjected to bending and torsion the authors introduce approximate expressions connecting the angle of crack in the vertical face with the ratio of the bending moment to the torsion moment. Using these expressions design equations are derived and it is shown that the results obtained using these equations are in close agreement with experimental results. D.R. Fairbairn and S.R. Davies
