BS 5268-2 provides guidance on the structural use of timber, glued laminated timber, plywood and other panel products in load-bearing members. It includes recommendations on quality, grade stresses and modification factors applicable to these materials when used as simple members, or as parts of built-up components, or as parts of structure incorporating other materials. It also gives recommendations for the design of nailed, screwed, bolted, dowelled, connectored and glued joints. In addition, it provides recommendations for a method of test to assess the adequacy of structural assemblies, and it includes general advice on workmanship, various treatments which can be applied, inspection and maintenance.
It does not, and it is not intended to, deal comprehensively with all aspects of timber construction. In particular it does not cover well tried and traditional methods of timber construction which have been employed successfully over a long period of time.
Compliance with the structural adequacy aspects of the Building Regulations can be achieved by following the recommendations of this standard or via National Technical Approvals Certificates.
