Recent announcements from RCA Forum and members.

Bridge manual, 3rd edition, amendment 4


Key updates, the first two of which are the most significant, are:

  • evaluation of bridges and culverts amended with the introduction of updated evaluation live load models (reference vehicles and axle groups)
  • addendums added to make interim provisions where significant changes in seismic hazard from previous requirements have been identified through recent research
  • combination of load effects amended, generally creating revised and new load combinations using existing load factors
  • steel fatigue design amended with new load model and design procedures
  • footway loading amended to reduce excessive conservatism in some elements of the loading
  • waterway design provisions amended extensively with updated key reference documents
  • introduction to low-damage seismic design added
  • bridge barrier provisions for cyclists updated.
