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.

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.
Entrant: Structural Dynamics Australia
Category: 4 ID Number: 4966
Location: Perth Zoo, WA
Client: Government of WA - Department of Finance
Completion Date: January 2012
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.
