This is the first design guide on concrete filled double skin steel tubular (CFDST) structures. It addresses in particular CFDST structures with plain concrete sandwiched between circular hollow sections, and provides the relevant calculation methods and construction provisions for CFDST structures. These inherit the advantages of conventional concrete-filled steel tubular (CFST) structures, including high strength, good ductility and durability, high fire resistance and favourable constructability. Moreover, because of their unique sectional configuration, CFDST structures have been proved to possess lighter weight, higher bending stiffness and better cyclic performance than conventional CFST. Consequently CFDST can offer reduced concrete consumption and construction costs. This design guide is for engineers designing electrical grid infrastructures, wind power towers, bridge piers and other structures requiring light self-weight, high bending stiffness and high bearing capacity.

Using steel and concrete together utilizes the beneficial material properties of both elements. Concrete filled steel tubes represent a good example of a concrete – steel composite structure, and are particularly useful as columns in high rise buildings and bridge piers. They can be used in a range of fields, from civil and industrial construction through to the mining industry. Several aspects of concrete filled tubes have received little coverage in existing design standards, design guides or relevant books, but are addressed here: construction methods or quality and their effect on performance, confinement, creep effects, pre-load effects, size effects, seismic behaviour and post-fire behaviour, worked examples under practical conditions, numerical simulations, mechanics models, concrete-filled double skin tubes, SCC(self-consolidating concrete)-filled tubes, HPHSC (high performance high strength concrete)-filled tubes, high strength steel and thin-walled tubes filled with concrete, and fiber reinforced polymer strengthening of concrete filled tubes. This book not only summarizes the research performed to date on concrete-filled tubular members and connections but also compares the design rules in various standards (Eurocode 4, AISI-LRFD, ACI, AIJ and Chinese Standard), and provides design examples. An invaluable guide for professionals and a detailed source of information for graduate students and beyond.

Steel-concrete composite structures, including concrete-filled steel tubular (CFST) structures and concrete-filled double skin steel tubular (CFDST) structures, have seen a significant increase in use in the modern construction industry due to their superior structural performance compared to conventional steel bare sections and reinforced concrete (RC) structures. Single Skin and Double Skin Concrete Filled Tubular Structures presents state-of-the-art in CFST and CFDST structures and their performance under various static loading conditions. The book establishes a foundation for understanding the structural performance of composite structures by discussing the behavior of CFST and CFDST structures based on experimental and finite element (FE) investigations. Besides, numerical and analytical methods for investigating the behavior of CFST and CFDST structures are presented in detail. The title offers many design examples following international design codes, including North American design guidelines ANSI-AISC 360, European design regulations Eurocode 4, and Australian design code AS 5100. The title can be used for the practical use of civil engineers and as a resource for further research. - Provides up-to-date advances on single-skin and double-skin constructions - Explains and illustrates the structural performance of columns, beams, and beam-columns - Discusses failure mechanism and gives detailed photographic references - Presents analytical and numerical investigations for the behavior of single-skin and double-skin constructions - Offers design examples following North American, European, and Australian codes
