SR125 Bottom plate anchors under NZS 3604:1999 (February 2004)

An assessment was made of the load demands on bottom plate anchors under both extreme events (windstorm or earthquake) and in-service loads (general robustness).

This showed that the provisions currently in NZS 3604 are generally satisfactory, but somewhat too high for internal walls.

An experimental study found that the common New Zealand practice of forming slab edges with concrete masonry header blocks is likely to result in an inferior performance by both generic and proprietary bottom plate anchors.
