Elephant Plasterboard QuickBrace Summary Guide Elephant Plasterboard QuickBraceTM Systems Extensive bracing tests have been conducted on Elephant Plasterboard. The bracing ratings published in this document have been obtained by independent testing and opinions sourced from New Zealand organizations with accredited quality assurance. Detailed in this document are some unique design solutions available to the New Zealand Building Industry to satisfy the bracing requirements of the New Zealand Standard NZS 3604:2011 Timber framed buildings.

Recent changes We have made changes and improvements to the QuickBraceTM Systems.



• Conservative Performances



A number of the performances published in this document has been revised downwards. This is solely for the purpose to provide the industry with conservative bracing designs. The previous publication (April 2014 Update) and QuickBrace software versions dated after November 2014 have some systems using a slightly higher performance. These higher values remain a correct reflection of how Elephant Plasterboard Bracing Systems perform.



• Revised Specification Numbering System

The numbering system has changed slightly to make it easier for the specifier, builder or building official to know whether a system requires Panel End Hold-downs (H) or not (N). The code “H” and the code “N” have been moved to the end of the numbering system. e.g. The system code ENSS becomes ESSN. Furthermore a “-” has been incorporated into some codes to indicate single-sided systems. e.g. The system code ESN becomes ES-N.

Bottom plate anchor placements have been reduced from 100mm to 80mm from the end of the bracing element. This is to be consistent with the bolt location when using bracing anchor brackets and represents industry best practise. This does not affect previous bracing designs or installations or performances.

• Changed Corner Pattern Layout



The “Typical” Bracing Corner Pattern previously required only on the ES-N and ESSN systems has been replaced by the “Condensed” Bracing Corner Pattern. Therefore 50, 50, 50, 50, 50, 50 and thereafter 150.



The Condensed Bracing Corner Pattern now applies to all QuickBraceTM Systems.



If the Typical Bracing Corner Pattern has been used on the ES-N and ESSN Systems then the performances published in this document and the more detailed Elephant Plasterboard QuickBrace Systems Manual 2015 will still be maintained



This change does not affect previous bracing designs, installations or performances. And has only been introduced in order to reduce the number of different corner patterns required.

If the installer has used the 50, 50, 50, 75, 75 and thereafter 150 corner pattern then this can easily be remedied by simply placing an extra screw between the next 150mm (where possible). Therefore 50, 50, 50, 75, 75, 75, 75 and thereafter 150.

* Timber Floors - It is required by NZS 3604:2011 to limit BU ratings to 120 BU/m for timber floors. For a higher floor frame uplift, a specifically engineered design will be required. Note- The QuickBraceTM Numbering System and the sub components thereof are protected by copyright.
