The Structural Engineer, Volume 70, Issue 22, 1992
The design of free-standing masonry walls Mr A. Aiken of Glasgow writes concerning an anomaly he sees in the treatment of the stiffening effect of piers on free-standing walls in BS5628: Structural use of masonry: Part 1: 1978 (1985): Clause 36.5.3 states that the design moment of resistance across the bed joints is given by (fkX/Ym + gd) x Z where ‘Z is the section modulus, which may take into account any variation on the plan arrangement, e.g. . . . piers . . .’ Verulam
The paper presents some design-office-type methods for large diameter and multilayered spiral strands with a minimum of equations and formulae. The proposed design methods are based on previously reported orthotropic sheet theory which, unlike previously published models, concentrates on the influence of interwire/interlayer contact phenomena as regards strand overall axial, torsional and free bending characteristics. M. Raoof and Y.P. Huang
Information Technology (IT) is one of those annoying but useful acronyms which covers both computing and communications. It has been used in the title of various projects in which the Construction Industry Computing Association (CICA) has been involved. D.H. Taffs
