A major strength of BRANZ Structural Engineering expertise is in its access to a range of highly sophisticated analysis tools (both commercially available computer packages and those specifically developed at BRANZ), the ability to derive basic system structural performance parameters by utilising the laboratory 'strong wall and strong floor,' and the depth of experience of its specialist staff. The Structural Engineering test laboratory is purpose-made and specifically equipped with fully calibrated equipment with an operating range and tolerance consistent with conditions experienced by building products and systems.

To determine the bracing rating of wall panel systems subjected to wind or earthquake according to the principles of AS 1649 or NZS 3604.

Dynamic system response

Shake table or pseudo-dynamic testing facilities to replicate and monitor real-time or extended-time response of building systems subjected to earthquake attack.

Elemental earthquake response

Ascertaining the response of suspended ceilings, curtain wall facade systems, building contents, items of mechanical plant and components within buildings to earthquake attack.

Wind face-loading tests

Pressure chamber testing of building envelopes (wall and roof cladding systems) both within the laboratory or on site according to the SIROWET facade test methodology.

In-service behaviour

Determining the serviceability compliance of building and floor systems subjected to actions associated with normal use, such as occupancy or externally induced vibrations, soft-or hard-body impacts or surface wear and abrasion.

Prototype testing

Demonstrating code compliance through prototype testing of new or innovative systems, either in the laboratory or in the field. Small-scale testing deriving fundamental mechanical properties using economical small- scale tests to be used as the basis of engineering computational methods of demonstrating system performance.
