Dr. T. M. Roberts (M)
(School of Engineering, University of Wales College of Cardiff)
Professor Dougherty has presented an interesting paper on the flexural-torsional buckling of doubly symmetric, laterally unrestrained beams subjected to combined uniformly distributed and concentrated gravity loading. However, the validity of the results presented is questionable, due to the neglect of a number of important parameters, such as the warping rigidity of the section, the height of load application above the shear centre, and, to a lesser extent, the influence of prebuckling displacements.

Stability, Strength, Elasticity and Thrustlines in Masonry Structures

The line of thrust has been popular in describing the stability of masonry structures since Hooke first described it. Many methods of computation have been developed which allow the derivation of a line of thrust for a particular set of loads on a structure. Most of these are flawed in that they neglect the many aspects of the problem which are not defined. W.J. Harvey

<h4>Discussion on Production of Structural Steel Sections by Ewart S. Andrews</h4>

Discussion on Production of Structural Steel Sections by Ewart S. Andrews

THE CHAIRMAN (Mr. J. Mitchell Moncrieff, M.Inst.C.E., Vice-president) said that members would agree with him that Mr. Andrews had furnished an interesting paper of an extremely practical kind, and he was now looking forward to seeing a kinematograph film which, he understood, would be projected to illustrate some of the things that had been said. The paper carried his mind back for thirty-five years, to the time when, as a young man, he designed a bridge in wrought iron, and it was put out to tender. The managing director of one of the tendering firms, an old friend of his, said, “Why did you design it in wrought iron?" He replied that he did so because more was known about wrought iron than anything else. His friend then said, “You should design it in steel.” He thereupon said that he would re-design it in steel, and he did so, on which his friend said, “But we have a lot of trouble in steel. Why, some of the bars we had in our yard last week cracked right across.” “In that case,” was his reply, "we had better go back to wrought iron.” The bridge, however, was built in steel.
