A Review of Information on the Settlement of Structures

THE PRESIDENT welcomed the visitors to the meeting, and introduced the authors.

Mr. I.L. GULYAS wrote that several logical mistakes appeared to have been made in the mathematical derivation of the equations used by the author. He also commented that using conventional eliminative methods of solution of equations the results arrived at by Mr. Turzynski could be arrived at with half the energy and time required by the methods of vector analysis used by the author. While welcoming the utilization of matrix notation for clarity in the solution of structural problems, it appeared that the author had shot at a sparrow with a cannon when a three millimetre air-gun would have been sufficient.

This paper reviews the methods available for the calculation of gravitational stresses in deep beams and presents the results of a series of experiments on such beams using the frozen stress method of photoelasticity in which gravitational loading was simulated in a large centrifuge. The stresses so obtained are given in a form suitable for use in design and a number of comparisons with theoretical results are shown. Professor A. W. Hendry
