Details are given of tests on eight web-tapered I-section steel columns. The members were half to one-third full size and were fabricated from plate by welding. The ends of each member were pinned, with torsion and warping prevented. In three of the tests lateral restraint was provided to one flange at mid-length. The loading in all cases comprised axial load, together with a major-axis moment applied at one end. Failure occurred by inelastic buckling. The behaviour compared well with results from a non-linear elasto-plastic computer program. Ultimate load capacities predicted by design Codes were found to be conservative. Modifications to the British draft limit-state Code for structural steelwork in buildings are proposed, to provide better agreement with the test results.

<h4>Verulam</h4>

Verulam

Mr Boyd Auger returns to our discussion of his article in Architects’ Journal from which we quoted (November 1979): My thanks to Verulam (March 1980) for his comments, with most of which I agree. On one point he is wrong. The RIBA now has over 80 members on BSI committees of which 11 are CSB. These include the committees concerned with CP 110, CP 112, BS 449 (B20), CP 2004 and CP 5628. Obviously, architects can play only a limited role on committees of this type, and few belong to any specialist subcommittees where much of the action is now concentrated. If there is any further correspondence on this subject I would be pleased if Verulam would correct this point. Verulam

Services Facility in the Pacific Northwest USA

This paper describes a structure that has been planned to be both a distinctive and an attractive building, blending with its wooded setting. It represents current practice for structures of this nature in the western states of the USA, and the paper describes some facets that are of general interest. C. Shearer

<h4>Discussion on Computer Applications for Detailed Design Calculations of Reinforced Concrete Structur</h4>

Discussion on Computer Applications for Detailed Design Calculations of Reinforced Concrete Structur

Dr. M. R. Hollington (M) (Cement and Concrete Association): I feel that my knowledge of computers is at the WL/8 stage, but nevertheless, during the past couple of years, I have become involved in the development of a system for producing reinforced concrete details by using a plotter. Today’s speakers have been talking about various methods for producing calculations, and Mr Craddock described how his program will produce the calculations and go right the way through to the drawings. We have tackled the problem from completely the other end and have looked at the drawing stage to see what a computer can do in this area.
