The Structural Engineer, Volume 62, Issue 14, 1984
In the course of redrafting BS5950, the successor to BS449, it was discovered that the common method of design for single-angle tension members connected by welding at the ends is based entirely on research for such members connected by bolting. A literature search failed to reveal any evidence for the use of the method for welded members and, as a result, a series of tests was carried out at the Polytechnic of Central London. This paper reports on those tests which confirmed the expected conservativeness of the BS449 method and suggests a simpler, less conservative approach. P.E. Regan and P.R. Salter
In tall structures the designer often has to deal with a major question in design, ‘what is the natural frequency of the structure, does it correspond to a known dynamic load, and, if so, how can the structure be altered to change that natural frequency sufficiently?’ G.M. Naief
