Showing typical material properties and dimensions; modifiers, and structural responses, it presents concise worked examples. Connections, an especially critical aspect of timber design, are thoroughly addressed. Relationships with other Eurocodes are explained, particularly those for EN 1990 Basis of Design. It cites British Standard - European Standard (BS EN) documents supporting the Construction Products Directive in structural timberwork. Copious references permit readers to investigate beyond the code background within the guide itself.
