Seismic Compliance and Non-Structural Elements (NSE)

Potter Interior Systems is master distributor of USG DONN suspended ceilings which have been manufactured in New Zealand for over 43 years — for New Zealand conditions and NZBC compliance.  As part of their seismic expertise, USG have a number of design solutions to make it easy for designers to specify the correct seismic resistant installations and easy practical components to assist the installers.

Depending on a number of key building and occupancy factors, their are two main seismic restraint methods; perimeter attachment, or if that’s not applicable or adequate then back-bracing/struts are usually required.  USG and their seismic engineers SKM, have numerous product and design solutions to cover most installations.

Equally important is the equivalent restraint of other services in and around the ceiling, which for NZBC compliance are to be installed in accordance with NZS 4219.  John Keen, Marketing and Technical Manager with USG, is fervent about seeing the closer working with services installation to avoid future potential collapses. "We have seen a number of cases — particularly as a result of the severe Canterbury earthquakes — where the poor old ceiling gets the blame for being on the floor, when the 300kg of equipment sitting on it, or unsupported HVAC has caused the collapse."

Currently there are a number of industry initiatives progressing to minimise NSE damage and subsequent work disruption, as well as the primary focus of further improving occupant safety.
