Comparison between bracing requirements using various codes and a proposed new set of bracing criteria

摘要

The notable increase in problems related to the bracing of tim - ber roofs clearly indicates that the time is ripe to seriously con - sider amended rules governing the design of such bracing. Burdzik et al have proposed a set of amended rules which are Founded on considering the stiffness of the bracing system as a Primary criterion. These proposed amended rules are compared With the existing bracing requirements of SABS 0163 (1994) as Well as with the requirements of the Eurocode, EC 5 (1992).
