Architect: Pritchard Francis
Structural Engineer: Pritchard Francis
Builder: The Slatter Group, WA
APPLICATION OF PROJECT: Zoological Enclosure
Structural Dynamics was contracted by The Slatter Group WA to assist with the design, material selection/supply and installation of a lightweight zoological enclosure that would cover an area of 90 meters long, 34 meters wide and 10 meters high.
The enclosure was covering two existing exhibits at the Perth Zoo, namely the penguin display and wetlands area, so needed to have minimal impact on the existing flora and infrastructure.
Pritchard Francis had already conducted the majority of the structural design and calculations of loads - Structural Dynamics assisted both The Slatter Group WA and Pritchard Francis with final material specifications to meet demanding requirements.
With such a large open enclosure that needed to be visually appealing for visitors as well as transparent for the exhibits inhabitants the challenge was to specify materials that met demanding load specifications but at the same time provided a light weight alternative that had minimal visual impact on the surrounding exhibits.
Other Structural Forms - Cablenets, Glazing, Facades, Spaceframes
The LSAA has groups of members interested in cablenets, high technology glazing and facades.
In fact one main reason for the creation of the LSAA from the MSAA was to cater for the growing number of projects which involved large glazed areas being supported by pretensioned cable truss systems or cablenets.
In modern times, when the overall energy usage for the life of a building is taken into account, the use of high technology facades will become more important. There is also a growing use of "green facades" or vertical gardens.
The traditional spaceframe structures are becoming rarer - those with many small elements that are man-handled and connected together on site. Labour costs and erection times are now outweighed by fewer larger assemblies that can be installed quickly by cranes.
The LSAA would welcome articles and links to projects in this category.

Pitt Street Lighting System
The City of Sydney turned to Ronstan to upgrade Pitt Street Mall's lighting to an energy-efficient catenary system as part of the overall redevelopment at the precinct. The result is a ladder-like series of lights supported by a Ronstan high-tension stainless steel cable framework.
The system illuminates the pedestrian areas below and the facades of the buildings, without needing large self-standing poles or heavy-looking supports. The 16m high tensile cable web is almost invisible, with bowstring support cables anchored every 20 meters into the facades of the buildings along the mall.
The catenary lights themselves comprise long tubes, combining downward illumination and a sequence of LEDs along the vertical length, which can be programmed for different colors depending on seasonal requirements – reflecting specific moods and occasions.
"The applications of tensile architecture are endless, thanks to its complex combination of engineering and design," says Rowan Murray, General Manager of Ronstan Tensile Architecture. "The Pitt Street Mall project is another example of this fact – and of the versatility, reliability and beauty of tensile forms."
The catenary lighting system at Pitt Street Mall comprises a twin longitudinal cable arrangement tied back to the surrounding buildings via spacers and guying cables. 23 customized tube style luminaires (lights) are suspended between 34 Marine Grade type 316 stainless steel ribbon catenary cables. The 1x19 strand cables are designed and manufactured to withstand up to 60 tonnes of tension, while resisting corrosion and stretch.
Pitt Street Mall reopened on December 6, 2012. In addition to Ronstan Tensile Architecture, the Sydney, Australia project team consisted of head contractor Westfield Construction, architect Tony Caro Architecture, cable and structural designers Enstruct Structural & Civil Engineers, building connections engineers Hyder Consulting and electrical contractors FIP Electrical.
