MS M. J. McDowell My question relates to the design of the arch. Did the designers consider the effects of uneven imposed loading on the floors causing an unbalanced load in the arch? If so, on what did they base their assumptions?
Recommended foundation depths in shrinkable clays On 18 January, Mr G. A. H. Trollope expressed the opinion that the minimum foundation depths in shrinkable clays on sites without trees, as recommended by the Building Research Establishment, were inadequate in that it was not reasonable to ignore the long-term likelihood of trouble from trees introduced within the presumed lifetime of the building concerned. Richard Driscoll (of the Geotechnics Division at BRE) considers the extent to which it would be feasible to adopt recommendations that would satisfy Mr Trollope’s criteria: Mr Trollope expresses concern about BRE continuing to find 0.9m-deep foundations for lowrise buildings acceptable on clay sites without trees. He suggests that trees are normally planted after site development and, therefore, that foundations should be designed to take account of ‘very likely future events’ and, in particular, of clay subsidence.

The process of moving to Europe-wide standards for structural steel is well underway and, within the next month, will take another step forward with the publication of EN 10 210: Part I which covers the technical delivery requirements for non-alloy and fine grain hot finished structural hollow sections. This standard will affect all British Steel Tubes & Pipes' hot finished structural hollow sections (SHS). E. Hole
