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

Mohamed Elchalakani Crawley is Senior Lecturer, and Director of the Structural Laboratory, at the University of Western Australia. He has published over 170 papers on the analysis and design of single skin and double skin concrete-filled tubular members.

Concrete-filled single skin (CFT) and double skin tubular (CFDST) members have advantages over concrete-filled steel tubular (CFST) columns. These include high strength and bending stiffness, fire performance, and ease of construction. CFT columns are made from a single-skin outer jacket surrounding a concrete infill, whereas a CFDST column consists of two concentric steel tubes with concrete in-fill. Despite the advantages CFT and CFDST hold over more conventional tubular columns, these structural elements remain relatively unused, there is a lack of understanding concerning their behaviour, and design provisions are lacking.
