Definition of a Lightweight Structure

Typical lightweight structures include cable-, membrane-, shell-, and folded structures as well as space grids, braced vaults and domes, arched-, stayed-and trussed systems. Membrane materials are commonly PVC-coated polyester fabrics as well as PTFE coated glass. Lightweight structures are widely employed in architecture, engineering and building construction and find application in long span roofs for stadiums and exhibition structures; covered shopping malls; entrance structures; signature structures and sculptures as well as shade and environmental protection canopies.

LSAA Ongoing Technical Subcommittee Work

Technical work being undertaken by the LSAA is currently focused on the PFAS environmental debate.

Recent attention has been on Fire Issues following on fires being spread up tall buildings because of inappropriate use of combustible cladding material.

LSAA Design Guidelines

This document has been issued for public comment and its aim is to document what is considered to be industry best practice.

It recognises that the field of tensioned fabric structures is a specialized area and the guidelines elaborate that these structures should be designed by close collaboration between competent and experienced persons.

LSAA Design Handbook

The Handbook is more in its early stages of development. The intention is to develop a definitive "Code" or "Standard" for the design and construction of tensioned membrane structures.

LSAA General

The Lightweight Structures Association of Australasia (LSAA) is a Not for Profit, autonomous, inter-disciplinary group of interested parties involved in the field of lightweight architectural structures. We started in 1981 as the Membrane Structures Association (MSAA) but expanded in 1994 to include other innovative structures such as cable-nets and high-tech glazing facades.

Operating primarily in Australia and New Zealand our basic aim is to promote the proper application of lightweight structures, their design, fabrication, construction and materials and to encourage the development of these and other aspects essential to lightweight structures.

Our mission is to "To lead, promote and develop excellence and innovation in lightweight structures by inspiring research and disseminating expert knowledge to expand the industry and opportunities for our members".

We do this by holding Conferences and our industry leading LSAA Design Awards.

Our members have completed outstanding structures around the globe and this enables us to draw on these contacts for our Conference Keynote speakers. These speakers also serve as Judges for our Design Awards and are able to recognize innovation and excellence.

Our members - whether they be architects, engineers, contractors, material suppliers or installers - are expected to adhere to our LSAA Code of Ethics.
