Cablenet 2

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. Articles are in random order.

LSAA 2011 Design Award Entry (Cat 2, 2019)

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.

Perth Zoo Wetlands & Penguin Enclosure 

PROJECT APPLICATION AND DESCRIPTION: 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.

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. 

 

LSAA 2011 Design Award Entry (Cat 5, 5042) 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.

Overview of Cablenet Structures

Australia can bost a very early cable net structure in the Sidney Myer Music Bowl in Melbourne.  

The modern cablenet structures burst on the international scene with the Expo 67 German Pavilion constructed in Montreal, Canada.

This was a larger version of the cablenet roof prototype designed by Frei Otto's team and used now to house the IL at the University of Stuggart.

 

This Project was entered into the 2016 LSAA Design Awards (5047)

Entrant: Taylor Thomson Whitting (Engineer)

Location: 50 Martin Place, Sydney.   Completed: Unknown   Client: Macquarie
Team: Johnson Pilton Walker, Taylor Thomson Whitting, Brookfield Multiplex, Sharvain Pacific Steel

Application: Glazed Roof over an Atrium.

Description: 

50 Martin Place was refurbished to provide a communal office from a very important heritage building. To increase light into the Atrium, the Atrium was increased in size by removing the perimeter slab, leaving the beams and columns. To provide maximum light, the roof was fabricated from glass. The final design incorporated a dome on steel trapezoid section suspending triple layer glazed panels, some of which were adjustable.
