The Structural Engineer, Volume 61, Issue 3, 1983
The importance of stability and the resistance to horizontal forces imposed on a building often do not receive the same attention as does the analysis for vertical forces. For all structures, it is essential that there be a path passing through clearly defined structural members by which the stabilising forces and horizontal forces may be transmitted to the foundations. Assumptions are often made in column design which allow the effective heights to be reduced on the basis that one or both ends are ‘properly restrained in position and direction’. These are often of doubtful validity. B.H. Fisher
The basic change in the design philosophy for bolted joints resulting from the adoption of limit state design, is outlined. The initial decisions the designer has to make are outlined and the pros and cons of bolted and welded site joints, on which such decisions must be based, are listed. The types of connector currently available are described. F.H. Needham
Mr C. Boswell (Health & Safety Executive): I am delighted to have the opportunity to open the discussion because the fact that Chris Wilshere’s paper is to be discussed by this Institution must surely signify that the Code of Practice has finally arrived after so many years of gestation. Mr Wilshere’s wide-ranging introduction to his paper this evening will probably stimulate a discussion across the whole field of falsework but I will limit my comments to one or two matters.
