This book details the theory and applications of finite element (FE) modeling of post-tensioned (PT) concrete structures, and provides the updated MATLAB code (as of 2019). The challenge of modeling PT prestressed concrete structures lies in the treatment of the interface between the concrete and prestressing tendons. Using MATLAB, this study develops an innovative nonlinear FE formulation which incorporates contact techniques and engineering elements to considerably reduce the need of computational power. This FE formulation has the ability to simulate different PT frame systems with fully bonded, fully unbonded or partially bonded tendons, as well as actual sliding behavior and frictional effects in the tendons. It also allows for the accurate simulation of anchor seating loss.

This second edition of Finite Element Analysis and Design of Steel and Steel-Concrete Composite Bridges is brought fully up-to-date and provides structural engineers, academics, practitioners, and researchers with a detailed, robust, and comprehensive combined finite modeling and design approach. The book's eight chapters begin with an overview of the various forms of modern steel and steel-concrete composite bridges, current design codes (American, British, and Eurocodes), nonlinear material behavior of the bridge components, and applied loads and stability of steel and steel-concrete composite bridges. This is followed by self-contained chapters concerning design examples of steel and steel-concrete composite bridge components as well as finite element modeling of the bridges and their components. The final chapter focuses on finite element analysis and the design of composite highway bridges with profiled steel sheeting. This volume will serve as a valuable reference source addressing the issues, problems, challenges, and questions on how to enhance the design of steel and steel-concrete composite bridges, including highway bridges with profiled steel sheeting, using finite element modeling techniques. - Provides all necessary information to understand relevant terminologies and finite element modeling for steel and composite bridges - Discusses new designs and materials used in highway and railway bridge - Illustrates how to relate the design guidelines and finite element modeling based on internal forces and nominal stresses - Explains what should be the consistent approach when developing nonlinear finite element analysis for steel and composite bridges - Contains extensive case studies on combining finite element analysis with design for steel and steel-concrete composite bridges, including highway bridges with profiled steel sheeting

Ordinary concrete is strong in compression but weak in tension. Even reinforced concrete, where steel bars are used to take up the tension that the concrete cannot resist, is prone to cracking and corrosion under low loads. Prestressed concrete is highly resistant to stress, and is used as a building material for bridges, tanks, shell roofs, floors

Post-tensioning is the most versatile form of pre stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.
