CHANDLER, BSc(Eng),PhD (London), MICE* G. L. HUTCHINSON, MEngSc, DPhil (Oxon), MIEAust, MICE Building code provisions for torsional coupling in asymmetric structures specify torsional moments in addition to lateral forces as the design loading condition. This Paper presents a systematic evaluation of the provisions for the secondary design torque applicable to structural elements on the stiffer side of the building, in relation to the centre of stiffness...

CHANA, BSc(Eng), PhD, MICE* A major difficulty in the development of a rational theory for shear design is identified as the lack of information on themechanism of failure. Experiments were systematically carried out to give an insight into the behaviour of reinforced beams, with particular reference to failure mechanisms. An experimental technique to measure dowel forces directly is developed, and experiments to investigate theimportant variables whichaffect the dowel strengthare described...

HEMSLEY, MEng, PhD, DIC, MICE, MIStructE* The plane elastic flexure of a thin infinite plate in frictionless and continuous contact with a homogeneous half-space is examined for symmetric and antisymmetric static applied loading. The integral relationships required to define completely the plate flexure are established by means of Fourier transforms; and, possibly for the first time, closed-form expressions are derived in terms of the exponential integral and related functions...

Simple closedform solutions are derived for a plate on springs under symmetric and antisymmetric loading, and numerical results are compared with those obtained previously for an infinite plate in frictionless and continuous contactwith a half-space...

DOVER, PhD, MIMechE, FINDTt In many areas of engineering such as the offshore industry, design and feasibility studies involve estimating the fatigue life of structural componentsunder long and complex random loading. Usually, power spectra representing different states of load history are obtained from dynamic stress analyses, and these spectra will be used to estimate the fatigue damage...

WILBY, BSc, PhD, FICE, FIStructE* In previous experimentation, the Author found that bars included in the compression zones of rectangular beams could reduce their strengths in shear. This applied to bars not designed to resist flexural compression, which, with little or no stirruping, were inadequately restrained from buckling. Practical examples of such bars are given in this Technical Note...

A. Hemsley and D. A. Spence Dr T. E. Glynn, Trinity College, Dublin The Authors have established a closed-form solution of the non-homogeneous differential equation forflexure of a thin plate on an elastic substrate. Their approach containsinteresting mathematical attributes quite apart from the practical significance of a bench-mark solution which solves a fundamental problem in the structural analysis of foundations and earth retaining structures...

N.Beal, R. H . Thomason & Partners As is common in literature on the subject, the Authors seem reluctant to define exactly what limit state design is or is not. Thusin Q 12 it is definedas `design with partial factors (reliability theory, level l)', whereas Q 14 accepts that the idea of limit states is not new and is implicit in current design methods; this is confirmed in Q 42, which also concedes that the extent to which partial factors should be used in real day-to-day design is `debatable'...

Low, Ove Arup and Partners,London This extension to the published theory on this topic is to be welcomed, and I have one comment.

Falconer, Structural Survey Partnership For some time now, our Company has been taking the lateral effects of fill into account in the assessment of masonry arch bridges, and it is surprising to learn that the Authors regard it as anew concept.
