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.
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 approached.
