Inspiring structures enclosing large spaces devoted to human endeavour or recreation, while minimising intrusion of bulky structural elements, continue to appear. The challenges demand inventiveness in design and ever greater rigour in the assessment of structural behaviour. Tubular frameworks have been the dominant form of structures in the world’s oceans, principally for oil and gas exploration and production, for obvious reasons of hydrodynamic efficiency, durability and containment or flotation. Hostile environments and hazardous operations combine to present enormous challenges to designers and operators. These challenges provide the cutting edge to fundamental research on tubular structures. Offshore structures are impressive demonstrations of form following function. Land based or offshore, tubular structures are at the leading architectural and technological edge of structural engineering. The art and science of both areas of application are enhanced by their presentation together, based on common forms and fundamentals. This volume contains papers drawn from fourteen countries, for presentation at the Sixth International Symposium on Tubular Structures, Melbourne, December 1994. Previous symposia in this series were held at Boston (1984), Tokyo (1986), Lappeenranta (1989), Delft (1991), and Nottingham (1993). Fundamental support from the start has been provided by CIDECT (Comite International pour le Developpement et l’Etude de la Construction Tubulaire), and HW Subcommis- sion XV-E, Welded Joints in Tubular Structures. Increasingly, the Symposium provides a forum for the rapid dissemination of information on new developments in CIDECT and Subcommission XV-E. Out of 121 submitted abstracts 83 papers were finally accepted after thorough review by a world wide panel, including the international and local committee members. Traditional areas of static and fatigue strength of connections are extended by reports of quality laboratory tests and finite element calculations. There are notable papers collating world data on strength and design formulae. A burgeoning area of beam-to-column connections in building frames using tubular columns is well represented. New areas of emphasis, perhaps reflecting interests in the antipodes, are hollow and void filled sections used in vehicle frames, and the incremental collapse of framed structures under high amplitude repeated load. It is fitting that on this first occasion in the southern hemisphere, the Symposium be held in Melbourne. The city boasts some inspiring tubular structures, reported at previous Symposia, and offshore in Bass Strait there are some fourteen steel platforms and two monotowers in production, some of which were the first to be built outside the Gulf of Mexico which were to experience significant fatigue loading.

The patient help of the Balkema staff, the constant and efficient administrative and secretarial support of Michael O’Brien, Maureen Kemp and Margaret Keegel, of the Office of Continuing Education, and the diligent support of secretaries Elizabeth Jeffreys and Noelene Deveson are also acknowledged. Without these people this volume would not have happened. List of reviewers The editors wish to acknowledge the efficient and diligent help of reviewers, including the following: A. Abel, V.Beck, I.
