Seminar - Peter Ansourian - Airline Hangar Trusses

Wednesday, May 26, 2004, 1.10 - 1.50 pm
Civil Engineering Lecture Room 3

Abstract

The talk will be an overview of the processes involved in the proof engineering of the largest hangar structure in Australia, the Qantas Heavy Maintenance Hangar at Brisbane airport. Structural concepts leading to the form adopted, taking into account Client's requirements, are developed. The innumerable load cases are reviewed, including permanent actions, temporary actions during erection, wind, earthquake, cranes, temperature and differential settlement. This is followed by an analysis that optimises the members selection. Stability considerations are paramount in a structure of this magnitude, and a close scrutiny of the designer's assumptions and methods is required. The design of every member and connection is reviewed. As the entire roof structure is assembled on the ground, the lifting process and temporary conditions are examined.
