Tubular Structures XIV Proceedings of the 14th International Symposium on Tubular Structures, London, Uk, 12-14 September 2012

Tubular Structures XIV contains the latest scientific and engineering developments in the field of tubular steel structures, as presented at the 14th International Symposium on Tubular Structures (ISTS14, Imperial College London, UK, 12-14 September 2012). The International Symposium on Tubular Structures (ISTS) has a long-standing reputation for being the principal showcase for manufactured tubing and the prime international forum for presentation and discussion of research, developments and applications in this field. Various key and emerging subjects in the field of hollow structural sections are covered, such as: special applications and case studies, static and fatigue behaviour of connections/joints, concrete-filled and composite tubular members and offshore structures, earthquake and dynamic resistance, specification and standard developments, material properties and section forming, stainless steel and aluminum structures, fire resistance, castings and fabrication innovations. Research and development issues presented in this topical book are applicable to buildings, bridges, offshore structures, entertainment rides, cranes, trusses and towers. Tubular Structures XIV is thus a pertinent reference source for architects, civil and mechanical engineers, designers, steel fabricators and contractors, manufacturers of hollow sections or related construction products, trade associations involved with tubing, owners or developers of tubular structures, steel specification committees, academics and research students all around the world.
