The Structural Engineer, Volume 44, Issue 4, 1966
Tests were made on 106 small-scale aluminium stanchions of I-section, loaded by an axial load P and one end moment M1 in the plane of the web; the slenderness ratios ranged between 27 and 79. For each slenderness the P-M1 relationship at collapse was well approximated by a parabola. G. Augusti and B. Barbarito
Although acceptable in most construction, the presence of shutter ties in unlined concrete water-retaining structures may form a potential source of leakage. This paper describes work undertaken to determine whether such leakage could occur and, if so, its practical importance and the factors influencing it. P. Jackson
Dr. A. J. Dutt (Senior Engineer, Special Structures, Greater London Council) said the London Museum Radio Tower-the tallest in this country-was one of the nicest buildings, and a centre of tourist attraction, not only from the point of view of functional requirements but also from the architectural point of view. Proper assessment of wind loading was one of the principal structural design considerations for these towers and Dr. Dutt wanted to raise a few points on that aspect.
