High Strength Steel Structures

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
