Mr. D. R. R. Dick (F): One of the subjects which interests me is insurance cover which is not merely cover for the contractors and sub-contractors, but for the client and the professional people as well, all under one policy.
The Halifax Building Society, the largest in the world, commissioned the authors' firm in January 1968 to design their new head office in the town of Halifax. The project, now completed is perhaps one of the most sophisticated office buildings yet constructed in the UK, being one of the first buildings to be equipped with a fully automated electronic filing and retrieval system. The main office accommodation is at high level, and the building is air-conditioned throughout all working areas, using a heat recovery method. The design and construction of the structural aspects of the building are described in the paper. W.E.W. Brook and H. Halsall
Several single-storey model scaffold towers were loaded to collapse to indicate the effects of different bracing arrangements and couplers. They were also analysed for overall elastic instability by means of a modified finite displacements program, which added deflexions to co-ordinates as the loading was increased. No allowances were made for elastic connections or for eccentricity of bracing. The finite displacements method was also used to analyse two three-storey Millshore towers which had previously been tested. Several conclusions are drawn about the effects of different bracings and couplers. The overall elastic instability predictions were found to be within 20 per cent for the model tubular scaffolds and close enough for design, i.e. within about 10 per cent, for the full-scale towers. Failure by lateral-torsional buckling of the second Millshore tower which incorporated open section puncheons was correctly predicted. A design recommendation is made for the effective lengths of scaffold columns. H.S. Harung, E. Lightfoot and D.M. Duggan
