Single Skin and Double Skin Concrete Filled Tubular Structures : Analysis and Design

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. Single Skin and Double Skin Concrete Filled Tubular Members presents the state-of-the-art on single-skin and double-skin tubular members, including their compressive and bending strength. The book grounds coverage in numerous published studies from the last few decades, reviewing research, and emphasising experimental and finite element (FE) work under axial compression, bending and combined action. The title offers examples of design following codes from N. America (e.g. ACI318); Europe (e.g. Eurocode 4) and Australia (e.g. AS 5100). The book considers the latest experimental results and design methods with different cross-sections, and makes recommendations for future research. This title provides a review of the most up-to-date advances in single-skin and double-skin concrete filled tubular members, for the practical use of civil engineers, and as a resource for further research.
