Post-Installed Rebar Guidance: Feedback Sought on Draft Document

Concrete NZ has collaborated with an expert working group to develop a Technical Specification on post-installed rebar, and is currently seeking industry feedback.

The current provisions of the Concrete Structure Standard NZS 3101:2006 Amendment 3 do not address post-installed rebar applications, therefore the purpose of the Technical Specification is to provide guidance for extending provisions of NZS 3101 for the stress development, detailing and splicing of reinforcement to post-installed rebar systems that are tested, assessed, and proven to perform in a similar manner to cast-in rebars. 

This Technical Specification provides design recommendations for post-installed rebar (PIR) connections loaded under static or cyclic (seismic) loads as well as providing guidance on the behaviour and design of post-installed rebar systems exposed to fire or elevated temperature. 

The target audience of this Technical Specification includes structural engineers, building consent officials, and academics.

You can access the public consultation draft by clicking here.

Feedback can be submitted to Concrete NZ by e-mailing admin@concretenz.org.nz.

The closing date for providing feedback is 25 October 2024.
