Are you looking for an earthquake rated cavity slider door?
Bris Aluminium’s cavity door slider has been independently certified (Form 15) to withstand seismic forces when tile is applied to the lining affixed to the cavity slider structures.
Doorways to bathrooms or toilets are the most common places where tiles would be applied alongside the sliding door.
This blog provides a summary of this certification and analysis, including which Australian Standards our signature cavity door sliding products meet.
J.C. Engineers were engaged to examine the compliance of the cavity slider against Australian Standards, namely AS 1170.4:2008 – Part 8: Design of Parts and Components.
Engineers have reviewed Bris Aluminium’s aluminium cavity slider components including:
- Cavity Slider Jamb
- Cavity Slider Channel
- Cavity Slider Double Brace
The analysis and Letter of Advice are limited to the seismic forces applied to the proposed cavity door slider system when tile is applied to lining affixed to the cavity slider structure.
In the event of an earthquake, the cavity slider jamb accepts the load from the braces and transfers it to the floor and lintel; while the carcass bracing accepts the load from the lining (plasterboard and tiles) – meaning you need to choose your aluminium framing solution carefully.
Cavity Slider Door Construction Overview
The wall should be constructed around the slider to conceal pocket part of the assembly in the wall. One or two sides of the wall lining secured to slider will be finished with ceramic tile.
The material is Aluminium Alloy 6060-T5. The door is proposed 35mm timber with the height up to 2.75m and proposed width up to 1.5m.
The cavity slider jambs combined with capping (vertical elements in the middle) and cavity slider carcass bracing SCB-23 (black horizontal elements) constitute the cavity for door.
The capping is produced in different sizes to accommodate different thicknesses of walls to fit standard sizes of the steel studs including 64mm, 76mm and 92mm.
Design Criteria: Seismic Activity and Cavity Door Slider
Bris Aluminium’s Cavity Door Slider was assessed against the following design criteria:
- Will not cause stress in slider components leading to plastic (non-rigid) deformations, and
- Deflection of the elements will not exceed limits imposed by the Australian Standards.
Cavity Door Slider with Tiles: Seismic Analysis
The certification shows that Bris Aluminium’s cavity slider is fully compliant to Australian standard under the following conditions:
- Maximum height of cavity sliding door is 2.75m
- Maximum width of Carcass Bracing SCB-23 is 1.5m
- Vertical spacing of the Carcass Bracing SCB-23 does not exceed 300mm on centre
- Maximum plasterboard thickness is 13mm
- Maximum weight of tiles does not exceed 13.2kg/m2 (typically, 5mm tile + 1mm glue)
- Structure importance level 2 (Normal structures I.e. residential)
- The seismic hazard design factor does not exceed 0.15 (Qld is below the established limit)
The analysis of the cladding system was conducted in accordance with the Australian Standards and the Industry practice. The loadings are referenced in the AS/NZS 1170.4 and combined in accordance with the load combination set in AS/NZS 1170.0.
