The Structural Engineer, Volume 44, Issue 4, 1966
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.
(As Dr. Sarkar was unable to be present, Professor Evans was supported in his presentation of the paper by Mr. M. G. A. Khalil.) Mr. L. F. Gliniecki (Associate-Member) asked whether a beam reinforced with mild steel would develop the same pattern of cracking as a beam reinforced with high tensile steel.
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
