The Structural Engineer, Volume 43, Issue 12, 1965
The paper deals with the calculation of plastic collapse loads for circular-arc beams built-in at their ends, subtending any angle up to 360° and loaded perpendicular to their planes. Neil Jackson
The present design procedures for reinforced and prestressed concrete are reviewed briefly. This forms the background for a discussion of the purpose of design and the phenomena meriting consideration in the design process; this discussion encompasses the developments that have been taking place in our understanding of structural behaviour and in the concepts of structural safety. The shortcomings of the present design procedures are then considered and a new philosophy of design, based upon the work of the European Committee for Concrete, is outlined. R.E. Rowe, W.B. Cranston and B.C. Best
Mr. W. J. Larnach (Associate-Member of Council) writes:- 'The author has described a useful method of analysis for frames satisfying his original requirement of complete similarity in each storey, even when this similarity includes a hinge as indicated in his Fig 1. When the similarity is not complete, then it appears from his remarks under " Other types of frames " that the application of his proposed method can become exceedingly cumbersome.'
