Commercial Structure Photo's

IMAGE 3: Detail inside Bunnings Warehouse. Joint of universal beams attached to roof, with vertical support post under apex, also shows bolt fixings.

The commercial building I chose to photograph was Bunnings Warehouse. I chose this building as it clearly shows the portal frame structure of the building. The overall picture (image 1) shows the long span of the building, made possible by the use of the portal frame. The interesting element (image 2) I chose to photograph was the universal beams attached to the roof, that didn’t have a support post under the apex. This is quite different to most of the other apex joints as they mostly have a post under the apex to help support the roof, as seen in image 3.

Note: Photo's used are from Bunnings Warehouse, 237 Colac Rd, Waurn Ponds.
