Projects in this category include non-prestressed structures such as domes and shells made from more traditional materials like concrete.

Prestressed structures may include saddle shaped cablenets, planar wall or roof glass surfaces supported by a stressed cable network.

Externally supported roofs (cable supported) also come into this category.

Taronga Zoo Chimpanzee Enclosure - Sydney 

APPLICATION OF PROJECT:   Separation Enclosure for Chimpanzees.

The Taronga Zoos’ chimpanzee troop is one of the largest captive groups in the world with recognized wild behavior patterns and a sophisticated social hierarchy.  With its population including four maturing sub-adult males jockeying and promoting themselves within the group, the zoo cited a need for the construction of a fully enclosed and semi-transparent separation paddock within the chimpanzee exhibit to allow the chimpanzees to be easily divided as needed, without moving them to an entirely new location, and thus avoiding potential commotion.

The Seperation Enclosure:

  • facilitates the introduction of new chimpanzee females to maintain the genetic pool.
  • provides the necessary infrastructure for the current troop management strategy and philosophies.
  • permits the troop to remain outside in summer unsupervised where this was previously not possible.
  • maximizes viewing time for the public.

APPLICATION OF PROJECT:    Zoological Enclosure

 4966 30

PROJECT DESCRIPTION:
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.

Cable Net Facade Feature - New Entrance

The redevelopment of Whitten Oval formed a pivotal piece in a plan to reinvigorate the western suburbs of Melbourne by providing services and facilities that would promote a sense of community. The plan had involvement from both State and Federal Governments and sort to place Whitten Oval at the centre of the community as a hub for local sporting and health service activities.

The Whitten Stand conversion, designed by Peddle Thorp Architects in Melbourne, called for a feature on the façade that responded to its context, was an identifiable entry, and provided an environmental benefit in the form of shading for the glazed façade behind. The resulting design was a series of floating panels that would display the team colours of the grounds home AFL team, the Western Bulldogs. The façade feature would run from the first floor to the roof acting as a gateway for supporters.

Ronstan Ribbons of Light

Ronstan Tensile Architecture provides full-service engineering, design assistance, and installation services for an innovative catenary lighting system that spirals through the Watergardens Town Centre in Taylor Lakes, Victoria.

Watergardens Town Centre is a 56 hectare community hub that offers shopping, dining, entertainment, hospitality, and other business services. The area has been a vibrant and growing part of Taylor Lakes township since its 1997 opening, attracting droves of visitors to its 200+ specialty stores and community events.

Recently, the Centre has expanded to include a dining-focused "eat street" called Station Streat, which is now outfitted with a custom Ronstan catenary lighting system. This system, designed by Electrolight and Ronstan, stylishly assists in making the area functional after dark without being obstructive to walking paths. More importantly, the system creates a spectacular entry statement with its unconventional 3-D "ribbon like" design that speaks to the geometric language of the Centre's existing graphic motif.

"The idea was to create a lighting scheme that gives a sense of movement and direction," explains Paul Beale, Director at Electrolight. "We endeavoured to create a visual link from the Centre's train station to the main entrance and shopping areas, while also highlighting the eddies of other parts in the complex that may have otherwise gone unnoticed."

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.
