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.

APPLICATION OF PROJECT:    Light weight structure used to control interior environment

 5202 01

PROJECT DESCRIPTION:

Aluminium tube sun shade screen designed by Fitzpatrick & Partners to control interior environment and to add to overall aesthetic impact of building.

Structural Dynamics Australia contracted by Colt International (sun shade fabricator and installer) to help design, supply and install stainless steel cable system to structurally support this element.

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.

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.

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.
