Volume 41, Issue 3
  • ISSN : 1021-2019



Problems attributed to the bracing of timber roofs have necessitated a fresh look at the bracing criterion given in the timber design code, SABS 0163 (1994). The difference between bracing provided for stability of the overall structure and bracing that is used to reduce the effective length of compression members is discussed. The differences between bracing at discrete intervals and bracing by means of a continuous elastic diaphragm are shown. Revised design rules are proposed, which, if implemented, should solve the problems currently being experienced with timber roofs.
