The Structural Engineer, Volume 10, Issue 12, 1932
MEMBERS of the Institution are undoubtedly keenly interested in the development of concrete construction. More general acceptance of concrete as a building material and a wider application of its use would be viewed by many as a desirable event. Some there may be who believe that world changes have already brought about conditions favourable to its early acceptance, not merely as a valuable contribution to all manner of construction, but as the chief medium of building. D.T. Lloyd Jones
Major JAMES CALDWELL (Member) (who was the author of the first paper presented to the Institution on the subject of welding) proposed a vote of thanks to Mr. Helsby, and congratulated him upon his paper, which had been prepared and published with a view to showing people in this country and overseas what could be done in the way of welded construction.
On pages 532 and 533 we publish a chart of Ferro-Concrete Sections, by Mr. A. D. Turner, which shows in a compact form the principles of calculation of all ordinary ferro-concrete members, including the complexities of bending plus compression. A point in connection with this contribution is that in case VI, the author appears to ignore the movement of the neutral axis which takes place when steel is introduced for taking compression stresses. This is done in other authoritative methods of calculation, and the error introduced in most cases is small and may be ignored without substantial error. It should be noted, however, that in special cases it might require further investigation.
