Structural timber design to Eurocode 5

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.

A Study of Semi-Rigid and Nonlinear Behaviour Of Nailed Joints in Timber Portal Frames

Abstract In this paper a study is made of the semi-rigid and non-linear behaviour of nailed knee joints in timber frames. A numerical analysis is applied to the non-linear deformation of the joints. The solution is derived using the stiffness method of analysis in which the rotation of each nailed joint is modelled by a series of piece-wise linear relationships, based on the load-deformation characteristics of nailed joints laterally loaded in single shear. The stiffness matrix is corrected at each step, to allow for joint flexibility; and the short-term non-linear deformation of frames, up to ultimate load, is calculated. Experimental verification is made using knee joint specimens and 6 m span timber portals with nailed plywood knee joints. The test results confirm the applicability of the analysis.
