The Structural Engineer, Volume 71, Issue 1, 1993
An analysis of coupled shear walls is developed which models planar coupled shear walls as a system of interconnected discrete structural elements. The analysis is based on the force approach, using as redundants the shear forces at the contraflexural points of the connecting beams. The redundant shears are determined by enforcement of compatibility of deformation on pairs of adjacent connecting beams. The resulting formulation is shown to be computationally advantageous for linear elastic static and dynamic analysis of coupled walls. The use of beam shears is shown to be particularly convenient for elasto-plastic analysis, with a perfectly elastic/perfectly plastic yield criterion, since the number of redundants progressively decreases as the analysis proceeds. The effectiveness and efficiency of the approach are demonstrated by application to an example for which solutions are available from a number of established alternative methods. D. Johnson and B.S.

This paper outlines the original development of a supermarket for J. Sainsbury plc on a methane-producing landfill site. The original store was among the first commercial developments in the UK on this type of site and was, therefore, of necessity innovative. P.D. George
Introduction: Part 3 The 1992 examination was attempted by 1065 candidates, a decrease of 45 on last year’s figure. The overall pass-rate of 38.2 % was down 1.1% compared with last year, and it remains disappointing to see the pass-rate below the 40 Yo mark. The total number of UK candidates was 674, of whom 292 passed, a passrate of 43.3%, slightly down compared to last year. The total number of overseas candidates was 399, an increase of 41, of whom 117 passed, a pass-rate of 29.3 %, a slight increase compared to last year.
