Experiments on Concrete of Different Cement Contents

PART VI. Prior to 1771, engineers who did not know each other very well often met accidentally in the Houses of Parliament and in the Courts of Justice, and frequently each stoutly maintained the superiority of his own opinions; and heated technical arguments were put forward for non-technical politicians to adjudicate upon. It was suggested to Smeaton that such a state of the profession was undesirable, and that it would be well if occasional meetings could be arranged where Civil Engineers might shake hands, and become personally acquainted, so that in this way, and by a friendly interchange of opinions on controversial subjects, and by a comparison of experiences, it might be possible to eliminate erroneous ideas and conduct their business “without jostling one another with rudeness, too common in the unworthy part of the advocates of the law, whose interest it might be to push them on, perhaps too far, in discussing points in contest.” E. Fiander Etchells

The subject of this paper is the strength of rectangular slabs, but it is limited to such slabs as have an appreciable thickness coinpared with the span, and more particularly it is limited to slabs of reinforced concrete only. A. Ingerslev

In calculating the strength of plated rolled or built up sections it is usual first to calculate the moment of inertia about the neutral axis and then divide by the distance of the neutral axis from the extreme fibre. W.A. Green
