Description

Proprietary wall bracing systems are commonly used to brace a building, but how are braced walls connected to a concrete slab?

In this article we look at both NZS 3604:2011 and proprietary wall bracing elements requirements.

Light Timber-framed buildings designed to NZS 3604:2011 Timber-framed buildings require braced internal and external walls to manage the loads placed on the building through the actions of wind and seismic events.

The designer calculates the relevant loads, both along and across the building, to determine the total bracing units (BUs) required to meet these loads. They then incorporate wall bracing systems made up of wall bracing elements to meet or exceed the load requirements.

Scope

• Range of types and capacities
• Follow manufacturer’s requirements
• Considerations with proprietary post-fixed anchors
  • Minimum capacity
  • Floor slab edge distance
