Dimensional Co-Ordination for Metric Structures

A series of tests is reported on 40 beams in which the total amount of steel and the amount pre-stressed was varied. Most of the beams were reinforced and pre-stressed with 5 mm (0.2 in) diameter wires, while there were a few tests of beams with pre-tensioned strand and beams with post-tensioned wires. The programme included tests under short-term, sustained and repeated loading. The results are used to analyse the stress in the tensioned and untensioned steel and to consider the factors affecting the flexural strength, crack width and deflection in order to make tentative recommendations for limit state calculations.

‘In 1919, 50 years ago, Ewart Andrews set up his private practice in London, as Consulting Engineer; I count myself most fortunate to have been one of his partners, and, now, very humble to succeed, after 35 years, such a one as he, and, after 10 years, such a one as my friend and present partner Lewis Kent, as President of this very fine Institution. To these two eminent structural engineers particularly, I owe my thanks: for their friendship, for their guidance and for their support, during almost 40 years in which I have been connected with engineering, of one sort or another.'

It is hoped that these reports of the performance of candidates in the Institution Parts 1, 2 and 3 examinations held in July 1969 will be of help to those who are preparing for future examinations and to those members and others responsible for teaching or guiding potential candidates.
