Past President of The Institution of Structural Engineers, Michael Dickson, concludes his review of the inspirational career of the German architect, Frei Otto. In this second part, Dickson discusses Otto’s later work – particularly projects in the Middle East and designs with low embodied carbon.
This article presents the design and construction of an unusual project. The HIVE is a building designed to act as the support framework for research into minimising the environmental impact of the built environment.
This month’s article from insurance broker Griffiths & Armour highlights the risks posed by strict liability provisions within contracts.
Sean Brady explores how the lessons of the 2014 Virgin Galactic crash are pertinent to all design engineers, irrespective of discipline.
According to the Construction (Design and Management) Regulations 2015, the standards of health and safety on site are not dictated solely by the contractor. This article discusses some ways in which clients can influence health and safety standards.
This article summarises the latest CROSS newsletter from Structural-Safety, including a report on serious concerns regarding an old fibrous plaster ceiling.
This article continues from the previous instalment in the series, and aims to guide engineers in assessing the extent of corrosion of steel frames and in selecting appropriate treatment methods.
The ‘Wood and Armer’ equations are well established as a means of accounting for torsional moments in bridge slabs. In this article, a potential source of misinterpretation of the original equations is identified and corrected. The misinterpretation is shown not to have significant implications for design, but may be of consequence where the Wood and Armer equations have been used for assessment. A number of other inconsistencies are identified and a revised set of equations is proposed.
In Timber Engineering Notebook (TEN) No. 21, the engineered wood product known as cross-laminated timber (CLT) was introduced. This latest article in the TEN series provides a more detailed introduction to the applications and use of CLT as a structural timber product, including structural benefits and benefits to the construction process.
Synopses of the latest papers accepted for publication in the Institution's new research journal, Structures. Access to Structures is free to all during 2015. From 2016, Institution members will continue to receive free access as one of their membership benefits. The journal is available online at: www.elsevier.com/locate/structures
We have Fairtrade foods, why not ‘fair-trade’ construction materials, or even fair-trade construction contracts? asks Pete Gates in an article discussing the wider impact of our actions as engineers, and considering the advantages of quantifying and measuring our impact.
David Edwards argues that the serviceability limit state for runway beams should be
considered to be slope, not deflection, meaning that current limitations are overly
conservative in most cases.
John Parker finds this collection of papers to be something of a mixed bag, with some very useful and well set out, but others less so. Overall, though, he concludes that it would make a good addition to the library of any engineer designing high-rise buildings.
