The Future for Steel

Hybrid structures We have received a letter signed jointly by Dr. D. D. Matthews, Chairman CSB/39 (concrete Code), and Mr B. A. Haseltine, Chairman CSB/33 (masonry Code): The January, February, May, June, and September 1980 issues of The Structural Engineer contained a running debate on the subject of the restraint of loadbearing masonry walls by precast concrete floors and the implications for the robustness of hybrid structures. We realise, from the correspondence to Verulam and from questions raised at other meetings, that this is a subject that is bothering many members of our profession. We thought, therefore, that it would be helpful if we gave our joint views on the subject. Verulam

It is postulated that there will be, in the future, an increasing pressure on structural engineers to take always the widest view possible. Designs should be created harmoniously, not merely to resist various actions in the best way but also to ensure quality of execution by taking sociological changes into account. Jan Bobrowski

This paper indicates why new materials and new construction techniques are difficult to introduce into the building industry, and draws attention to the fact that loads are more effectively carried by tension than by compression. It concludes that gross deformation structures are bound to be developed in the future. Professor E. Happold
