Class 10 building resource
What loads are considered when designing a Class 10 building?
Structural design checks the actions that may affect a building during its intended life and how they combine. For an ordinary domestic Class 10 project, these commonly include the structure's own weight, use of the building, wind and site-dependent environmental actions.

Direct answer
weBeta determines the structural actions applicable to a suitable QuickFrame10 project. Before ordering, provide the exact site and proposed building arrangement. The intended use and any related loading details can be clarified during the remote consultation.
The NCC and the loading framework
The National Construction Code establishes structural performance requirements and referenced design pathways. AS/NZS 1170.0 sets out the general structural design basis and how actions are considered together. The other parts address particular types of action. The applicable pathway still depends on the confirmed building classification, jurisdiction and project conditions.
Permanent and imposed actions
AS/NZS 1170.1 addresses permanent actions, such as the self-weight of framing, roofing, walls and fixed components, and imposed actions associated with the intended use and access. A garage, storage area, roof or other occupied or accessible surface may have different design considerations.
Wind actions
Wind may be determined through AS4055 for a suitable building within that Standard's scope and limits, or through the more general project-specific AS/NZS 1170.2 pathway. Wind affects the framing, bracing, cladding support, connections, tie-down and load path to the ground. A site wind classification is an input to design, not the completed structural design.
The distinction is explained in AS4055 vs AS/NZS 1170.2 for wind.
Snow, ice and earthquake actions
AS/NZS 1170.3 covers snow and ice actions where the project location makes them relevant. AS 1170.4 covers earthquake actions. Their significance depends on the site, building and structural arrangement; customers are not expected to determine this before submitting the project.
Domestic use and unusual loads
QuickFrame10 is intended for ordinary domestic Class 10 loading, including household vehicle parking where relevant. Retaining loads, vehicle-impact design and other unusual loads are outside QuickFrame10.
What QuickFrame10 collects
The structured intake records the site, proposed roof and wall arrangement, heights, openings, roofing and available supporting documents. weBeta uses that information to establish the applicable loads and design the framing, bracing, tie-down, connections and foundations for a suitable project. Material-specific references are summarised in the QuickFrame10 materials and design standards guide.
Official structural provisions
The Australian Building Codes Board publishes the National Construction Code editions. State and territory variations and adopted editions should be checked for the project jurisdiction.
