High Strength Steel Structures

Behavior and Design of High-Strength Constructional Steel presents readers with extensive information on the behavior of high-strength constructional steels, providing them with the confidence they need to use them in a safe and economic manner to design and construct steel structures. The book includes detailed discussions on the mechanical properties of HHS while explaining the latest progress in research and design guidelines, including material properties at ambient and elevated temperatures. In addition, the book explains the behavior of elementary members subject to different types of loads and load combinations, and those that are integral to the design of bolted and welded connections. The hysteretic behavior of HHS materials and members are also discussed. This is critical for application and designs under earthquakes and fire conditions. The buckling behaviors of HSS box-section and H-section columns are included in terms of experimental and numerical investigations, along with the geometric imperfection induced by welding. Provides a comprehensive review on the topic of high-strength constructional steel and the latest progress in research and design guidelines Explains the behavior of elementary members subjected to different types of loads and load combinations Recommends structural systems for using high-strength constructional steels in seismic zones

High-strength materials offer alternatives to frequently used materials for high-rise construction. A material of higher strength means a smaller member size is required to resist the design load. However, high-strength concrete is brittle, and high-strength thin steel plates are prone to local buckling. A solution to overcome such problems is to adopt a steel-concrete composite design in which concrete provides lateral restraint to steel plates against local buckling, and steel plates provide confinement to high-strength concrete. Design of Steel-Concrete Composite Structures Using High Strength Materials provides guidance on the design of composite steel-concrete structures using combined high-strength concretes and steels. The book includes a database of over 2,500 test results on composite columns to evaluate design methods, and presents calculations to determine critical parameters affecting the strength and ductility of high-strength composite columns. Finally, the book proposes design methods for axial-moment interaction curves in composite columns. This allows a unified approach to the design of columns with normal- and high-strength steel concrete materials. This book offers civil engineers, structural engineers, and researchers studying the mechanical performance of composite structures in the use of high-strength materials to design and construct advanced tall buildings. Presents the design and construction of composite structures using high-strength concrete and high-strength steel, complementing and extending Eurocode 4 standards Addresses a gap in design codes in the USA, China, Europe and Japan to cover composite structures using high-strength concrete and steel in a comprehensive way Gives insight into the design of concrete-filled steel tubes and concrete-encased steel members Suggests a unified approach to designing columns with normal- and high-strength steel and concrete

Material Properties of Steel Fire Conditions is a major new contribution on how to understand the material properties of steel in fires. The application of new types of steel and development of sophisticated codes of practice has grown dramatically in recent years, making this a timely resource on the topic. Under fire conditions, knowing the material properties of steel is essential in the fire resistance design of steel structures, such as in Eurocode3. This book shows that the reduction factors of mechanical properties of different steels are quite different. In recent years, the authors of this book have carried out significant testing on the material properties of several types of steels, such as Q460 steel, Q690 steel and A992 steel, etc. Users will find this new test data on the material properties of steel with temperature useful in evaluating the fire resistance of steel structures in their own projects. Deals with the material properties of steels in fire conditions, including thermal properties and mechanical properties, such as thermal conductivity, strength, elastic modulus and creep behavior Provides basic knowledge to perform fire resistance design of steel structures Presents information useful to designers, researches and students who must conduct fire resistance design or perform structural analyses on high strength steel structures

High-strength steel (HSS) is critical to modern buildings and civil engineering structures. Novel research, methods, and designs are continually being developed. High-Strength Steel Structures presents advances in the fundamental mechanical performance of HSS structures, and design guidance and methods for practical engineering. The book considers the fundamental behaviour of HSS structures, including their material properties, and sectional residual stress distribution, long and stud columns subjected to compression, and seismic performance. The volume presents the latest advances from a leading research group, based at Tsinghua University in China, and most of the findings described here are new to national or international standards. The book gives details on the experimental, theoretical and numerical studies that went into the mechanical performance, design methodology and engineering application of an innovative structure system. Six chapters introduce HSS structures; consider their material properties; the residual stress modelling of HSS sections; the overall building behaviour and local buckling behaviour of HSS columns; and finally the seismic behaviour of HSS structures. This title offers a comprehensive reference for practicing engineers and architects, and a blueprint for future studies on the design and practical engineering of HSS structures. Presents the latest research and advances in high-strength steel structures Presents findings not yet covered by national or international standards Describes a range of experimental programmes on high-strength steel structures including their data Details robust scientific design methods for high-strength steel structures with typical structural elements Offers innovative design methodologies, as well as research methodologies valuable for future research

TRB's National Cooperative Highway Research Program (NCHRP) Report 679: Design of Concrete Structures Using High-Strength Steel Reinforcement evaluates the existing American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications relevant to the use of high-strength reinforcing steel and other grades of reinforcing steel having no discernible yield plateau. The report also includes recommended language to the AASHTO LRFD Bridge Design Specifications that will permit the use of high-strength reinforcing steel with specified yield strengths not greater than 100 ksi. The Appendixes to NCHRP Report 679 were published online.
