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.

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.
