    Design Guide for Steel-Concrete Composite Columns with High Strength Materials - An Extension of Eurocode 4 Method to C90/105 Concrete and S550 Steel

    Design Guide for Steel-Concrete Composite Columns with High Strength Materials - An Extension of Eurocode 4 Method to C90/105 Concrete and S550 Steel

    The design guide is written with practicing structural engineers in mind. It emphasises professional applications, placing great emphasis on ready-to-use materials. It contains formulas and tables that give immediate solutions to common questions and problems arising from practical work related to composite columns. The design guide also provides good detailing practices for typical joints between steelconcrete composite columns and other structural components. Guideline is provided to select matching concrete and steel grades for the design of high strength composite columns. Special considerations for fire resistance design, fabrication of high tensile steel sections, and preparation of high strength concrete are emphasized. This design guide will endow structural engineers with the confidence to use high strength materials in a safe and economic manner to design and construct high rise buildings.

    Advanced Design and Optimization of Composite Structures I

    Advanced Design and Optimization of Composite Structures I

    This course introduces the basic components of an airframe structure and discusses their use and limitations. The realities of composite design such as the effect of material scatter, environmental knockdowns, and damage knockdowns are discussed and guidelines accounting for these effects and leading to robust designs are presented. The resulting design constraints and predictive tools are applied to real-life design problems in composite structures. A brief revision of lamination theory and failure criteria leads into the development of analytical solutions for typical failure modes for monolithic skins (layup strength, buckling under combined loads and for a variety of boundary conditions) and stiffeners (strength, column buckling under a variety of loads and boundary conditions, local buckling or crippling for one-edge and no-edge-free conditions). These are then combined into stiffened composite structures where additional failure modes such as skin-stiffener separation are considered. Analogous treatment of sandwich skins examines buckling, wrinkling, crimping, intra-cellular buckling failure modes. Once the basic analysis and design techniques have been presented, typical designs (e.g. flange layup, stiffness, taper requirements) are presented and a series of design guidelines (stiffness mismatch minimization, symmetric and balanced layups, 10% rule, etc.) addressing layup and geometry are discussed. On the metal side, the corresponding design practices and analysis methods are presented for the more important failure modes (buckling, crippling) and comparisons to composite designs are made. A design problem is given in the end as an application of the material in this Part of the course.
