Discussion on Load Testing of Concrete Building Structures by J. b. Menzies, D.S. Jones and C.W. Oli

ISE or ICE, a difference As befits the journal of a learned society, scanning of the galleys by the editors is meticulous; nevertheless, with such a small staff, the occasional slip escapes attention, as evinced by our own gaffe, for which we apologised in May. In that same issue Mr A. S. Crockett found his literary sensibilities shocked by an exercise in ‘licence’ with spelling which he clearly considers ought not to be practised’. He writes: I have been following the responses to Finniston by the Civils, Municipals, and Structurals very closely, not least because of being a member of the Council of the Municipals and a member of the President’s Advisory Committee which has dealt at considerable length with the report itself and the responses thereto from the Institutions.

A method has recently been proposed for the design of unbraced, multistorey steel frames to limiting values of horizontal deflection. It is shown that this permits an approximate value for the lowest elastic critical load to be quickly calculated. Study of a typical frame demonstrates that in many cases the result can be expected to be sufficiently accurate for use in design. D. Anderson

Methods are now available for the design of composite columns with concrete casings of normal density aggregates for the design of both bridges and buildings. Here the counterparts of these methods are given for casings of lightweight aggregate concretes. The full report describing their derivation is held in the Institution’s library under reference X70.
