The Structural Engineer, Volume 54, Issue 11, 1976
In this paper the behaviour of reinforced and unreinforced masonry is considered. Tests on eccentrically-loaded unreinforced walls and couplet specimens are reported and a simple theoretical approach for solid block masonry is derived. A method of predicting wall strength is presented. Additional tests are described on reinforced masonry sections subjected to lateral loading only and the simple ultimate load theory used for reinforced concrete is shown to give a good indication of the ultimate strength of the sections. The effect of employing different values of the partial factor of safety for strength of the masonry is considered. It is indicated that present design procedures using permissible stresses result in uneconomic design. W.B. Cranston and J.J. Roberts
Various means are commonly used to rectify lack of straightness in stiffened steel panels to bring them within working tolerances such as those stipulated in the Merrison Rules for box girders. The paper describes tests to establish whether panels straightened by various heating, jigging and over-loading procedures have the same strength as panels fabricated to meet those tolerances without resort to such procedures. The panel proportions and modes of testing were designed to produce in all cases collapse by failure of the outstand. It was found that, while straightening procedures which caused compressive residual stresses in the outstand left the panel with a decreased capacity in compression, procedures which left a tensile residual stress could restore the full carrying capacity.

The President: Good evening, ladies and gentlemen, and welcome to this rather special meeting, which is a combined one with the the British Group of International Association for Bridge and Structural Engineering. As well as welcoming all those of you in the body of the hall, we have a number of special guests that I would mention. First and foremost, Professor Leonhardt and Frau Leonhardt, and of course of Professor Leonhardt more later. We have Baroness Sharp, Dr. and Mrs. Feilden, Sir Hugh Wilson, Sir Charles Husband, Mr. Philip Gooding, and Professor Baker.
