This volume contains the Kurobane lecture and proceedings of the Tenth International Symposium on Tubular Structures - ISTS10, held in Madrid, Spain, 18-20 September 2003. The ISTS10 provides a platform for the presentation and discussion of seventy-three lectures covering themes including: bridges; roofs; design aspects and case studies; static joint behaviour; fatigue; members; beam-column connections; finite element methods; concrete filled tubes; trusses and frames; cast nodes; and behaviour of tubular structures under fire. This book provides a useful reference work for architects, civil and mechanical engineers, designers, manufacturers and contractors involved with tubular structures.
