9.1 Structural Performance
The Hebel PartyWall system can be either a loadbearing or non-loadbearing wall. The Hebel PowerPanel within the wall system is non-loadbearing with the exception of self weight.
9.2 Construction Loadings
During construction, the Hebel PowerPanel could be subject to wind loading. The builder shall provide the necessary temporary bracing of the panel until both structural frames are installed.
Note: The screw connections may not be adequate to stabilise the panel against construction loadings.
9.3 Cutting of Hebel PowerPanel
The standard Hebel PowerPanel can be reduced in length by cutting 150mm maximum from each end, and to a minimum width of 270mm. All exposed steel reinforcement shall be liberally coated with the Fentak anti-corrosion coating available through CSR Hebel.
9.4 Wall Frame
The wall framing presented in this Design Guide for various wall systems are nominated for the acoustic and fire performance values. It is the designer’s responsibility to determine an appropriate wall framing system to satisfy structural adequacy. Several items the designer must allow for are:
- lateral loadings
- wall height
- deflection limits
- offset distance (gap) from the panel
- building movement
- control joint locations
9.5 Wall Height
The overall wall height limit is 12m for both 75mm Hebel Intertenancy 001 and 75mm Hebel Intertenancy 002. The wall shall be constructed of Hebel PowerPanel of 3000mm maximum length. Walls constructed with panel lengths exceeding 3000mm are outside the scope of this guide.
9.6 Earthquake Loading
Earthquake loading has not been considered in this design guide. It is the designer’s responsibility to ensure the connection system has adequate capacity to resist any imposed earthquake loading.
9.7 Fixings
Fasteners & Fixings
Most screw fixings are timber type, which is sufficient for penetrating the metal thicknesses outlined in this design guide. Connections that have larger metal thicknesses may require a metal type screw and will need to be designed and approved by the project engineer.
Fixings – Deflection head track to substrate
The fixing to secure the angles and tracks to the concrete slab shall be capable of withstanding a shear load of 0.75kN. For high wind pressures during construction, the designer shall determine if mechanical fasteners are required:
- Drive pins and concrete nails (check size and suitability for fire rated situations with the manufacturer);
- 8mm diameter mechanical fasteners.
Table 9.1 outlines the connection type and requirements for constructing 75mm Hebel Intertenancy 001 and 75mm Hebel Intertenancy 002 detailed in this design guide.
