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

Concrete-Filled Double-Skin Steel Tubular Columns: Behavior and Design provides a thorough review of the recent advances on the behaviour and design of concrete-filled double-skin steel tubular (CFDST) columns. Drawing on their extensive knowledge and research, the authors cover topics such as different CFDST columns under axial compression, innovative techniques including the use of rubberised concrete, columns with different cross-sections, and steel material envelops and failure modes. This book is an overview of research carried out by this highly experienced and leading research group with specialist knowledge in the topic. It is an invaluable resource for researchers, graduates and post-graduate civil engineers and civil engineering designers.

Provides a comprehensive overview of advances on the behaviour and design of concrete-filled double-skin steel tubular (CFDST) columns over the past decade Gives deep-dive explanation of important concepts such as the void ratio which makes these girders different from conventional concrete-filled steel tubular (CFST) columns Explains the failure modes of short and slender columns under compression, with detailed illustrations and photos from both real-life and virtual tests performed by the authors Presents in-depth analysis of the ultimate strengths of CFDST columns with different steel envelops and concrete infills Makes a detailed comparison with available international codes, such as Eurocode 3, and provides recommendations for future studies Discusses new innovative confining stress-based design for different types of CFDST short columns

Geopolymer Concrete Structures with Steel and FRP Reinforcements: Analysis and Design focuses on structural behavior, including the aspects of compression, bending strength and combined action of GPC members, with the book's content based on published studies over the last two decades. Geopolymer concrete (GPC) structural members reinforced with FRP reinforcement have some advantages in resisting forces compared to conventional concrete or steel tubular members. Among the most important are the high strength and bending stiffness, fire and impact performance and favorable, construction ability and durability.

To this end, there are no significant applications of these new structural elements worldwide, partly due to the lack of the understanding of their behavior and insufficient design provisions in different design manuals. This book, therefore, seeks to highlight their characteristics and future potential.

Provides comprehensive, up-to-date advances on Geopolymer Concrete (GPC) reinforced with steel and FRP bars and stirrups construction with a summary of over 100 papers published in the last decade Compares the behavior and failure modes between Geopolymer Concrete (GPC) structures and Ordinary Portland Concrete (OPC) structures Explains important concepts such as bond, confinement, fracture of stirrups and buckling of FRP bars Includes an in-depth analysis of ultimate strength of GPC and OPC, considering governing failure modes Presents design examples following international standards, including North America ACI 440.1R-15, Canadian CAN/CSA S806, and Australian such as AS 3600
