Announcements

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.
