The design of the roof trusses for the Siessa Ramabodu Stadium (winner of the tubular category for the SAISC @steelawards 2016) at first sight look as if they could be upside down for gravity loads, until you realize that the main compression chord bifurcates into 2 chords in the high stress region. Some of the details the engineer has thought through well are: 1 top channel toe down to support top of brickwork makes for a great looking detail 2. The connection between the stadium side cantilever trusses and the backside fascia supports is well thought out and the tie between the 2 end plates was adjusted in length to sort out the inevitable inaccuracies on the radial setting out of the concrete columns 3. The double chords of the fascia trusses worked well to creAte the stepped fascia details 4. The use of CHS girts to the fascias eliminated the need for what would have been a very complicated sag system.
This large warehouse for the company Amrod, suppliers of corporate gifts, had an extremely short program. From date of order the steelwork contractors had 13 weeks to fabricate and erect 440 tons of steel. This required them erect approximately 10 tons of steel per day to be able to meet the program. The team faced many challenges in making this program work, like the tilt up walls, earth works and rain delays as well as the interface of many other trades. Ferro Eleganza are very proud to say that this was achieved and quality assurance never went by the wayside.
The structural framing includes
- Lattice roof structure consisting of girders and trusses.
- Metsec purlins.
- Steel columns sitting on concrete columns.
- Metsec Cladding rails bolted to outside of steel and concrete columns.
From a cladding perspective – various colours and plain levels were utilised giving the outside of the warehouse an aesthetic appeal. Klip-Tite sheets were rolled on site, as they were too long to transport.
The client was very satisfied with the project and also handed over on time. It is a truly beautiful warehouse that is well visible to all passing the Buccleuch interchange.
