Improvements in Bolted Joint Efficiency by the Addition of a Cold-Setting Resin Mixture

Mr. R. TAYLOR :- THE Authors are to be congratulated on their presentation of a new approach to the problem of the effects of shear on the ultimate strength of reinforced concrete beams. The original conception of Laupa, Siess, and Newmark of expressing on a moment basis the strength of beams loaded in such a way as to give a ‘shear-compression’ type of failure has been extended by the authors to cover all types of failure.

THE PRESIDENT introduced the Authors who, in turn, presented the particular sections of the paper with which they were primarily concerned.

I. Introduction THE iteration method of frame analysis developed by Dr Ing. G. Kani, has proved to be extremely satisfactory for the analysis of any type of conventional multi-storeyed building frame under any given loadingl,2. The Author proposes to extend this method to the solution of more complex structures of the type shown in Fig. l , where a column continues through more than one floor without any beams connected to it. Frames of this type are met with frequently in the design of factory structures. It may be mentioned from the outset, that the fundamental ideas of Dr. Kani are only slightly modified so as to cover such complex frames. The method has however been explained from first principles to make the paper complete in itself. B. N. Thadani
