The Structural Engineer, Volume 58, Issue 6, 1980
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. J.B. Salter, D. Anderson and I.M. May
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
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.
