The Structural Engineer, Volume 43, Issue 7, 1965
Mr. E.N. Underwood (Past President), invited by the Chairman to open the discussion, said he had thoroughly enjoyed the authors’ clear description of what was a masterpiece of bridge engineering. He agreed with the Chairman that lessons learned from Brunel and Robert Stephenson could only emphasize what brilliant engineers they had been. Modern experience had proved that their systems could be applied economically today in spite of all the other modern developments.
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. H. McCallion and N.F. Rieger
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.'
