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.

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.
Overview of Cablenet Structures
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.
Australia can bost a very early cable net structure in the Sidney Myer Music Bowl in Melbourne.
The next structure, and the most famous is the impressive stadiums for the Munich Olympics designed by Frei Otto.
Highly stressed cable trusses are also used to support flat glass surfaces now common for facades.

South Australian Health and Medical Research Institute (SAHMRI)
SAHMRI is a world class facility for medical research under construction in Adelaide (July 2015)
The facility will increase the ability for new leading edge research and clinical applications into better treatment and potential cures for the most challenging diseases.
The building has an interesting curved facade as illustrated in the following images.
