Professor A. C. Scordelis writes:
‘I have read with interest the paper by J. E. Gibson and was pleased to note that his computer solution checks the results obtained in an earlier study of mine. Dr. Gibson’s early pioneering work in the development of computer programmes for cylindrical shells and the publication of his books and papers have been a stimulus for
similar work being carried out in the United States.'
A simple design procedure is outlined for calculating the bending moment and torque which will cause a plastic hinge to form in an I-section member. The effect of restraint of warping of the cross-section on the torque carrying capacity is taken into account. Experiments on the torsional strength of I-sections with warping restraint and on the combined action of bending and torsion show the proposed design method to be safe and suitable for the design of I-section members under these conditions.

Equations which express end bending moment and end shearing force for a heavy elastic bar in a generalized state of vibratory motion are obtained, in terms of end transverse displacements and end rotations. These equations may be used to facilitate the solution of problems of vibration in systems of rigidly connected bars. The example of a simple portal frame is considered.
