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.

Jagged Edge - Queenstown NZ

PROJECT DESCRIPTION

An Atypical design and Construct project involving a house for a confidential client. The design was prepared and presented as a “Design+Construct” package that was purchased as a package by the Client. The Builders Team had prepared preliminary documentation based on advice from specialist consultants and Architects. The design was then proposed for sale to the market as a complete delivery vehicle.

The project is a residential building built on the side of hill with an impressive vantage point. The main goal of the design is to maximise transparency to optimise the view.

The bedrock of the mountain is used for the foundation of the roof which is suspended projecting towards the lake. The project utilises tension cables and clamps to support the glass façade panels.

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.

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.
