Summary

Structural Timber Design to Eurocode 5 is a comprehensive book which provides practising engineers and specialist contractors with detailed information and in-depth guidance on the design of timber structures based on the common rules and rules for buildings in Eurocode 5 - Part 1-1. It will also be of interest to undergraduate and postgraduate students of civil and structural engineering. The book provides a step-by-step approach to the design of all of the most commonly used timber elements and connections using solid timber, glued laminated timber or wood based structural products. It features numerous detailed worked examples, and incorporates the requirements of the UK National Annex. It covers the strength and stiffness properties of timber and its reconstituted and engineered products; the key requirements of Eurocode 0, Eurocode 1 and Eurocode 5 - Part 1-1; the design of beams and columns of solid timber, glued laminated, composite and thin-webbed sections; the lateral stability requirements of timber structures; and the design of mechanical connections subjected to lateral and/or axial forces as well as rigid and semi-rigid connections subjected to a moment. The Authors Jack Porteous is a consulting engineer specialising in timber engineering. He is a Chartered Engineer, Fellow of the Institution of Civil Engineers and Member of the Institution of Structural Engineers. He is a visiting scholar and lecturer in timber engineering at Napier University. Abdy Kermani is the Professor of Timber Engineering and R&D consultant at Napier University. He is a Chartered Engineer, Member of the Institution of Structural Engineers and Fellow of the Institute of Wood Science with over 20 years' experience in civil and structural engineering research, teaching and practice. The authors have led several research and development programmes on the structural use of timber and its reconstituted products. Their research work in timber engineering is internationally recognised and published widely. Also of Interest Timber Designers' Manual Third Edition E.C. Ozelton & J.A.
