J. Avent (Conservation Accreditation Register for Engineers)
This article aims to discuss some of the issues, challenges, tools and techniques available to the practising structural engineer when assessing existing structures. While the article focuses principally on floor structures, the techniques can be used on a range of applications to provide an understanding of how existing structures are actually behaving, rather than how we might think they are working.
James Miller brings this series to a close by looking back over ground covered and forward to a bright future in which conservation accreditation is increasingly valued and engineers are able to innovate through the application of emerging technologies.
The authors recently conducted a study into the elastic behaviour of thin (Kirchhoff ) plates using commercial finite-element (FE) software. In attempting to verify the FE solution, it was compared to results presented in Timoshenko’s Theory of Plates and Shells and a significant difference was observed. This article presents the work conducted to uncover the reason for this difference and reveals an error (probably typographical) in the text. The source of the error is identified and it is demonstrated how such errors might propagate into other texts on the subject of plates. The significance of the error to the practising engineer is also discussed.
This article is the first of two which will discuss the problem of corrosion of steel
frames behind masonry elevations. It aims to provide an introduction to this form of
construction and to consider the ways in which lack of maintenance can lead to corrosion of the steel frame, before setting out how remedial work should be
