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.
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 this article, issues associated with the scaffolding of historic structures are briefly explored and illustrated through four case studies. These are projects that crossed the author's desk, as a consulting engineer specialising in the conservation of historic structures, within a few months of each other. They explore some of the constraints imposed by 'historic fabric' and other factors, the compromises made, and the solutions reached.
