Design of Steel-Concrete Composite Bridges to Eurocodes

Abstract

The conceptual and detailed design of composite bridges in accordance with Eurocodes, the suite of European Standards covering structural design of all civil engineering works, including bridges, is covered in this book. Included in the codes are prescriptive normative rules regarding safety factors, loads and their combinations, material properties, required verifications and analysis methods; bridge design is strongly based on these codes, as well as other issues that are included. The design for a majority of composite bridge superstructures is addressed in this book, and readers are guided through the selection of appropriate structural bridge systems. Software supported analysis models are proposed, required verifications for sections and members at ultimate and serviceability limit states are outlined, including fatigue and plate buckling, as well as deck and bearings seismic design. The main types of common composite bridges are presented, structural forms and systems are discussed, erection methods and preliminary design aids are described. Railway bridge information is provided, but road bridges through the design examples are the focal point. Fatigue analysis and design, fatigue load models, detail categories, and fatigue verifications for structural steel, reinforcement, concrete, and shear connectors are presented. With an emphasis on reinforced elastomeric bearings, structural bearings and dampers are also covered. This book is useful for bridge designers, structural engineering students, or for those needing to convert from other codes to Eurocodes, such as practicing engineers.
