Mr. Barron: The authors say that the terms of the contract should conveniently be those of a building contract which would be most appropriate for the much more costly superstructure. They actually used the RIBA conditions, more usually referred to as the JCT standard form. They could have also or alternatively used the ICE conditions modified for work with high architectural content. Did the JCT form prove to be as convenient as expected?
A common means of forming a rigid joint between universal beam and column sections is to weld an end-plate to the beam end and then to bolt to the column flanges. Tests on models of he tension region of beam-column moment connections joined in this manner, and also complete joints, have shown that the behaviour of the beam tension flange force upon the end-plate and column flanges can be represented by isolated T-stubs. Typical modes of failure for this type ofjoint are discussed relative to experimental observations, and the yield-line method is then used to predict column flange and end-plate flexural yield loads. Good agreement was achieved with test results. A limit state design method is proposed for extended end-plate joints having four bolts in the tension region, and from which stiffening requirements can be readily assessed where necessary. J.A. Packer and L.J. Morris
Mr. T. N. W. Akroyd continues the discussion of the engineer's responsibilities in law and the significance of the Lord's decision in Anns' case in a lively and informative way. He writes : Why do engineers write passionately in emotive language about matters which need to be thought out carefully, logically and unemotionally? A rhetorical question, perhaps, resulting from the consumption of wine and Verulam in unequal quantities but due in particular to the letter from Mr. Tietz on the subject of Anns' case (August 1977).
