NZS 3101 Amendment 3 Published

Wednesday, 4 October 2017  
NZS 3101:2006 Concrete structures standard sets out the minimum requirements for the design of reinforced and prestressed concrete structures. The Standard provides a means of designing and verifying compliance with the NZ Building Code.

The Canterbury earthquakes showed that some aspects of the current design Standards needed updating. The Canterbury Earthquakes Royal Commission of Inquiry and the Structural Engineering Society NZ (SESOC) made several recommendations to amend NZS 3101, some of which have been implemented via Amendment 3.

Also, in March 2017, an investigation into the performance of Statistics House following the November 2016 Kaikoura earthquake began. Some actions specific to NZS 3101 were recommended, and these are addressed in his Amendment; specifically the impact of beam elongation on precast floor systems, maintaining composite connection of the precast flooring to the in situ topping, and precast floor support details.
