The paper reviews the methods of predicting the settlement of structures on spread footings and piled foundations. It reports settlement observations on structures and model tests. Reference is made to the stiffness of the structure and its effect on settlement. The limits of permissible settlement to prevent cracking or damage are discussed. S. Rosenak
The paper describes an experimental investigation into the structural behaviour of a particular type of bolted beam-column connexion, in which the connexion consists of a plate welded to the end of a beam and fastened to the flanges of the column by pretensioned high strength bolts. Some recommendations are made as to the plastic design of the component parts of such an assembly and general conclusions are drawn which may affect the plastic design of many types of bolted connexions.

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