A relatively new book about the incredible legacy of physical models used for designing and understanding of lightweight structures has been published by Spector Books (part summary below from their website).
In the 1950s, Frei Otto’s tent structures left their mark on the horticultural shows of the new Bonn Republic; together with Behnisch & Partner he created the roof landscape for the Munich Olympic Games in 1972. The innovative potential in his work is based on the interdisciplinarity of a mode of thinking that took in architecture, technology, art, science, and society. He saw nature as a model and tried throughout his life to harness it for the sake of architecture and civil engineering — and thus also for the future.
An updated Second edition of AS 4174:2018 "Knitted and woven shade fabrics" has been released.
It replaces the first edition published in 1994.
The main contents are:
Section 1 Scope and General
Section 2 Horticultural Shade Protection Fabrics
Section 3 Human Shade Protection Fabrics
Appendices - 6 Appendices
[Update August 2019: There has been an Amendment No 1 issued with some revised wording and typo corrections]
The Second Annual Summit Conference being held in Melbourne from 25-26 June 2018 will be concentrating on the Fire Issues pertaining to dangerous cladding in particular.
Details of the event can be found at the following webpage, from which the text below is extracted with acknowledgement.
"2017 was a tragic turning point for the construction and safety industry with the Grenfell Tower fire in London. For Australia, it was a particularly sobering reminder of the narrowly avoided disaster at Melbourne’s Lacrosse Tower fire in 2014.
As governments, taskforces, regulators, and industry bodies continue to work together to ensure that no such tragedy happens again, the much broader discussion around non-compliant products and accountability has come into focus. In addition to the risks associated with some cladding products, the sector is coming under further scrutiny on topics such as glass, wiring and waterproofing."
A new (future) draft version of the NCC (National Construction Code) is now available for public comment. Comments are due by COB April 13 2018.

Of interest to many involved in lightweight structures, and in particular tension membrane structures, are the new requirements related to fire. These new requirements have been the result of a number of fatal fires in Australia and overseas. See this article for an interim report related to fires and cladding.
An Interim Report has now been published by the recently formed Victorian Cladding Taskforce.
The taskforce follows the serious Lacrosse Building fire in Melbourne Docklands (November 2014) and later the Grenfell Tower disaster (71 fatalities, June 2017) in London (see Grenfell_Tower_fire ) involving the use of highly combustible cladding panels.
Prepared by the Tensile Membrane Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE
Standard ASCE/SEI 55-16 provides minimum criteria for the analysis, design, and performance of membrane-covered cable and rigid member structures, collectively known as tensile membrane structures. It is applicable to both permanent and temporary structures.
Within CEN/TC 250/WG 5, CEN/TC 248/WG 4, the TensiNet Association and COST Action TU1303, an international team of researchers, engineers, architects, material producers and manufacturers has been working on this report, which provides background information in support of the implementation and development of a future Eurocode for the Structural Design of Tensile Membrane Structures.
Tensioned Membrane Structures have unique properties compared to the more conventional built environment. Besides their low self-weight and high flexibility these structures are known to be 'optimally' constructed, as they are only loaded in tension. It results in shapes adapted to the flow of forces and a minimum of material needed to realise the span.
Important revisions have taken place for fire detection and control in buildings across a number of Standards.
These set out the minimum requirements that should be in place during design and construction to ensure compliance.
Recent revisions include:
The use of ventilation and air conditioning in buildings - Fire and smoke control in buildings
Fire detection, warning, control and intercom systems - System design, installation and commissioning
Fire detection, warning, control and intercom systems - System design, installation and commissioning - Emergency warning and intercom systems
Article added February 2016. For more information, see SAI Global website
The Australian Building Codes Board have recently published a new standard for Temporary Structures.
The LSAA contributed to its development.
This Standard is intended for use in the design, construction and use of temporary structures. It provides criteria for structural safety (particularly determining appropriate wind actions), fire safety (including fire resistance of materials, fire safety services and equipment, and egress), access, sanitary facilities and certain ancillary provisions.
It is still open for adoption by particular State or Territory Authorities.
