The Structural Engineer, Volume 5, Issue 10, 1927
It is a favourite pastime of historians, indeed, it is part of their job, to designate certain events as marking the date of the commencement of definite epochs. J.G. Kay
Much reinforced concrete work has been executed during the last few years, and the average practitioner is frequently brought up against the problem of evidences of presumed deterioration or assumed faulty details of design or workmanship that time or wear and tear apparently brings forth. Structures that, when built, embodied generally the best of design and the skilled attention of the best workmanship, are frequently found bearing traces of incipient dilapidation or the marks of a fatigue that on the face of it seem neither to have been anticipated nor provided against. Excluding the possibilities of damage by shock or percussion, one finds here and there a seaside pier whose concrete deck has stood well for years, whilst the beams underneath have in many places "peeled" from the tension rods and laid them bare. Again, a crane-road beam, obviously heavy enough for its duty, is in a similar condition. In another case, a short series of heavy floor beams were installed that should have been 15 ins. deep, but were put in at 12 ins. owing to exigencies for head-room, and they stood, and are still standing. They were given "plenty of steel." A.T. Ricketts
