A Limit State Design Method for the Tension Region of Bolted Beam - Column Connections

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). Verulam

The need for experimental work in connection with lateral loading has been explained in Part 1. There is no less a need for a suitable design method based on experiment and, where possible, experience, that can be used in the limit state revision of CP lll . Part II discusses the possible design approaches that could make use of the data now available. B.A. Haseltine, H.W.H. West and J.N. Tutt

Part l describes flexural tests on smallmasonry specimens and tests on full-sized walls, without preload, up to 5.5m long and 3.6m high, uniformly loaded laterally by means of air bags. Results for 6l different clay bricks and three mortars have enabled characteristic flexuralstrengths to be related to the water absorptions of the units. A few results for concrete block walls are also reported. H.W.H. West. H.R. Hodgkinson and B.A. Haseltine
