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 book highlights the residual strength of the CFDST column, that can be used to determine the most suitable repair method in order to retrofit the column. The book elaborates on the behavior of CFDST column after being exposed to fire. This book also discusses the effectiveness of repair method using single and Hybrid Fibre Reinforced Polymer (FRP) of fire-damaged CFDST columns. It concludes by taking a look at different parameters such as thickness of outer steel tube and fire exposure time as factors affecting thermal properties/stability.

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.

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

This book offers a clear and comprehensive overview of both the theory and application of fundamental aspects of concrete-filled double steel tubes (CFDST). Many analysis and design applications are presented, which involve mechanical components and structural members often encountered in engineering practice. This monograph is written for practicing structural and civil engineers, students, and academic researchers who want to keep up to speed on the latest technologies for concrete-filled steel tube (CFST).

This book introduces the approach of Machine Learning (ML) based predictive models in the design of composite materials to achieve the required properties for certain applications. ML can learn from existing experimental data obtained from very limited number of experiments and subsequently can be trained to find solutions of the complex non-linear, multi-dimensional functional relationships without any prior assumptions about their nature. In this case the ML models can learn from existing experimental data obtained from (1) composite design based on various properties of the matrix material and fillers/reinforcements (2) material processing during fabrication (3) property relationships. Modelling of these relationships using ML methods significantly reduce the experimental work involved in designing new composites, and therefore offer a new avenue for material design and properties. The book caters to students, academics and researchers who are interested in the field of material composite modelling and design.
