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

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.

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

Tubular Structures XVI contains the latest scientific and engineering developments in the field of tubular steel structures, as presented at the 16th International Symposium on Tubular Structures (ISTS16, Melbourne, Australia, 4-6 December 2017). The International Symposium on Tubular Structures (ISTS) has a long-standing reputation for being the principal showcase for manufactured tubing and the prime international forum for presentation and discussion of research, developments and applications in this field. Various key and emerging subjects in the field of hollow structural sections are covered, such as: special applications and case studies, static and fatigue behaviour of connections/joints, concrete-filled and composite tubular members and offshore structures, earthquake and dynamic resistance, specification and standard developments, material properties and section forming, stainless and high-strength steel structures, fire, impact and blast response. Research and development issues presented in this topical book are applicable to buildings, bridges, offshore structures, cranes, trusses and towers. Tubular Structures XVI is thus a pertinent reference source for architects, civil and mechanical engineers, designers, steel fabricators and contractors, manufacturers of hollow sections or related construction products, trade associations involved with tubing, owners or developers of tubular structures, steel specification committees, academics and research students all around the world.

This textbook focuses on concrete-filled steel tubular structures formed by placing concrete inside the steel tube. It deals with the mechanical essence of concrete-filled steel tubular members in compression/tension, bending, torsion, shear and the combined effects, the working mechanism of concrete-filled steel tubular members under long-term load, cyclic load, fire exposure and post-fire exposure, and proposes practical design methods based on experimental and theoretical studies and parametric analysis. The content addresses some key technical issues of concrete-filled steel tubular members, such as the mechanical properties of steel and core concrete, the shrinkage and creep of core concrete, the bonding behavior between steel tube and core concrete, the limiting values for the initial stress of steel tube caused by construction load and the void of core concrete, the protective design of concrete-filled steel tubular members under chloride corrosive environment and impact loading, etc. This textbook also discusses the technology and design principles of concrete-filled steel tubular hybrid structures.
