Peritas was requested to achieve a high springing clearance, a low maximum roof height (by modern standards) and a 30m x 30m column grid. Consequently, our engineers decided on using a traditional portal frame supported by girder trusses.
To achieve an efficient design, we carefully considered the wind loading, taking into account the orientation of the building and its surrounding region. Once confident of the correct loading as per the Australian Standard for wind load, we modelled the entire building in 3 dimensions in our advanced structural analysis software. This allowed us to minimise all structural sections to the most efficient, yet compliant size.
The structural internal slab consists of large fibre reinforced panels with no saw cuts. Every floor joint is reinforced with armour edging to guarantee minimum maintenance for the owner and maximum performance for the occupier.
A stable soil base allowed us to utilise efficient pad footings to support the structure.
