Timber joists are one of the most basic structural elements found in many timber frame construction. They are closely spaced timber beams (typically in the range of (450-900mm) used to support a suspended ceiling, timber flooring or sheathings. In this article, we shall discuss the design procedure of timber joist. All advice given will be based on the guidance and recommendations of BS EN 1993-1-1:2004 Eurocode 5 Design of Timber Structures- Part 1-1: General common rules of buildings.
