Plastic Design in Reinforced Concrete Written Discussion on the Paper by Professor W. T. Marshall, B.Sc. (Eng.), Ph.D., M.I.Struct.E., M.I.C.E.

DR. W. W. L. CHAN, (Associate-Member) referred to the section given in the paper on Hinge Rotation. Whilst the Author first recognised that Hinge Rotation occurred over a finite length, and was governed by the depth of neutral axis, he then quoted permissible rotations of 0.001 radians and 0.01 radians for unbound and bound sections respectively as being Professor A.I.I,. Haker’s suggested values and used these figures in the worked example of the built-in beam.
