Gravitational Stresses in Deep Beams

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.

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.
