(As Dr. Sarkar was unable to be present, Professor Evans was supported in his presentation of the paper by Mr. M. G. A. Khalil.)
Mr. L. F. Gliniecki (Associate-Member) asked whether a beam reinforced with mild steel would develop the same pattern of cracking as a beam reinforced with high tensile
Although acceptable in most construction, the presence of shutter ties in unlined concrete water-retaining structures may form a potential source of leakage. This paper describes work undertaken to determine whether such leakage could occur and, if so, its
practical importance and the factors influencing it.
Professor A. L. L. Baker (Member) opened the discussion by saying that he agreed entirely with what the authors had said in their presentation but not with what they
had written in the paper. He agreed with the statistical, probabilistic approach. It was obviously the only logical way of dealing with the variations of strengths of materials and the variations and vagaries of loading. There were one or two points in the paper which Professor Baker found slightly misleading. First of all, the matter of basing a design entirely upon a probability of failure-10-7-and a minimum cost, and saying that one could not entirely guarantee a structure against failure, needed some qualification. He thought this was rather a dangerous statement.
