New Zealand Transport Agency Bridge Manual: recent amendment for seismic resistant design, and future directions

In December 2004, Transit New Zealand issued a provisional amendment to the Bridge Manual introducing revised earthquake loading and concrete durability requirements. Dramatically different draft requirements proposed for the New Zealand Standards NZS 1170.5 and NZS 3101, undergoing revision but with finalisation having become protracted, had undermined the credibility of the previously existing Bridge Manual requirements. Since then, both revised New Zealand Standards have been published, and a detailed review undertaken of the Bridge Manual seismic design requirement. A Land Transport NZ research project: "Review of AS 5100 Australian Bridge Design Code with a View to Adoption" has been concluded, and a number of design and construct projects have been tendered. A number of issues have been identified from these that need to be addressed.
