The Structural Branch of EA, Victoria Division in conjunction with the
Lightweight Structures Association of Australasia would like to invite you to a technical seminar

RAS Night


Engineering Principles of Tension Membrane Structures

Tuesday Afternoon October 28th 2008 at EA Auditorium, 21 Bedford St, North Melbourne

Tensioned membrane structures have become an important structural form for both large span roof structures as well as for smaller covered areas which also serve as an architectural statement.

The design principles and fabric material properties needed to be understood for a successful realization of a project are not covered in University courses. This seminar is an opportunity to learn about the basic structural design parameters, material selection, fabrication and erection techniques.

Topics which will be presented

  • Brief history of tensile structures
  • Understanding fabric materials
  • Understanding the supporting structures
  • Understanding the engineering design process
  • Fabrication, construction and installation processes
  • The future directions for lightweight structures


Dr Kourosh Kayvani – President LSAA and Principal, Structural Group (NSW) of Connell Wagner who has been responsible for the design of the new Wembley Stadium roof in the UK amongst other major projects.

Ian Knox – Managing Director of Innova International and LSAA member representing the architectural textiles industry, identifying and reviewing major technical fabric groups.

Rowan Murray – General Manager Ronstan Architectural and LSAA Secretary with specialist knowledge of cables and fittings needed in most structures.

Peter Lim – Managing Director, Tensys Engineers - Specialist Consultants for Lightweight Structures. Peter has been recognized for his fine work with numerous International Design Awards.

David McCready – Life Member of LSAA with decades of design, fabrication and installation experience of tension membrane structures.

Dr Peter Kneen – Executive Officer LSAA who is a pioneer structural engineer in Australia in many areas of lightweight structures.

Conference and Seminar Proceedings from the MSAA and LSAA Events.

Additional content available to current LSAA Financial members

The LSAA holds its Conference in a variety of locations and where possible a site visit is arranged to inspect a new project.

There will be some articles added that show images taken during those visits.

This category, available to current LSAA members, show a collection of pictures taken at the Conference Dinner and Design Awards Ceremony.

At most LSAA Conferences a Workshop is held and this category is a collection of the images taken at the various events.
