The test results of twelve reinforced concrete beams subjected to sustained torsional moments for periods of up to two years are reported. The average rotation after one year was over five times the rotation due to the initial application of the load. The effect on the long term torsional rotation of different intensities of sustained torque and of different link spacing is discussed. C.D. Goode
Lt.-Col. N. D. Clifford, MBE, RE: As a mere military engineer I shudder at the thought of trying to make any technical points in front of such an august audience. I would, however, like to make one or two philosophical points.
Computer simulated tests on axially loaded, pin ended, welded steel columns are reported. The tests took account of strain-hardening, initial lack of straightness and a variety of residual stress distributions and magnitudes. Design curves for light to medium column sections are suggested. B.W. Young and K.W. Robinson
