The Structural Engineer, Volume 65, Issue 10, 1987
Bending moments in brickwork panels Mr A. Aiken's letter, published in July, has prompted several replies. Mr J. E. Saul writes to us from Mold, Clwyd: Mr Aiken's problem is that he has not realised that brick panel design in BS5628: Part l is based on plastic principles. Well mostly, that is panel analysis is, but section analysis is not that is elastic. Anyone could be excused for making this mistake since, apart from being confusing, it is also well wrapped up by the Code writers. Verulam
The paper proposes some rules for selecting bed-joint reinforcement in brick facade walls which may be susceptible to settlement. Loading criteria are adopted in preference to deformation criteria, and the importance of specifying a minimum amount of reinforcement and of the need to provide ductility is emphasised. The use of the equations is demonstrated on a four-storey wall. Professor I.A. MacLeod
A form of limited continuous construction: suitable for use in multistorey buildings designed as non-sway frames, is described. The method employs a two-way grid of beam and continuous tibs sitting on double spine beam which pass on each side of the columns. Fabrication and erection are thereby simplified. A number of design issues raised by the use of continuous composite beam, continuous beam restrained by roof decking and columns subject to biaxial bending are discussed in the light of both current Codes of Practice and recent research.
