Concrete Composite Columns
Concrete Composite Columns: Behavior and Design focuses on confined concrete and establishes analytical methods for each composite column. The volume moves beyond existing resources to study the relationship between existing composite structures and design methods for the sectional form of a concrete composite structure. Chapters cover the failure criteria of concrete, confined concrete types, models, including axial stress prediction, analysis and design-oriented constitutive models, the design and analysis of section form, axial and seismic behaviors of concrete composite columns, the seismic design of concrete composite columns, and the engineering application. This book offers a practical solution to students, researchers, and engineers working with both steel and FRP-confined concrete composite columns. - Focuses on confined concrete and provides analytical methods for composite columns - Discusses different types of composite columns, including FRP and steel-concrete composites - Considers the construction method and confining forces in composite concrete columns - Details confined concrete from basic theoretical analysis to seismic behaviors and design methods - Provides a solution to students, researchers, and engineers working with confined composite columns
Prefabricated Steel-Reinforced Concrete Composite Column
In conventional concrete-encased steel composite columns, a steel section is placed at the center of the cross section. Thus, the contribution of the steel section to the overall flexural capacity of the column could be limited. For better efficiency and economy, particularly under biaxial moment, the steel section needs to be placed at the corners, rather than at the center of the cross section. Recently, a prefabricated steel-reinforced concrete column has been developed to utilize the advantages of the reinforced concrete column and the steel-concrete composite column. In the composite column, four steel angles are placed at the corners of the cross section, and transverse bars and plates are used to connect the angles by welding or bolting. The composite column has been widely applied to industrial buildings that require large sized columns and fast construction. In this chapter, the newly developed composite column is introduced, and basic mechanism, structural performance, and field application case are discussed.

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
