Miscellaneous of building and deflection lorry overhangs535 Index538xContentsPrefaceIt is 18 years since the publication of the previous edition of this MANUAL , duringwhich time the TIMBER engineering industry has undergone many changes. Mostnotable is the harmonizing of British Standards with European practice and therecent release of BS 5268-2:2002 Code of Practice for permissible stress design,materials and workmanship which moves design concepts closer to those given inEurocode 5 Design of TIMBER Structures.
