Preface of Design of Steel Concrete Composite Bridges to Eurocodes PDF

Bridges have a strong symbolism as they connect opposite sides. It is not a coincidence that bridges are illustrated on one side of Euros. For many engineers, bridge design assumes top priority in their practice. In fact, the design of the optimal, technical, economical, and aesthetical solution with existing tools and means is a challenge for any structural engineer. International best practices show that the search for alternative solutions and the choice of the optimal one are essential for the construction of a successful bridge. The criteria for selection may be governed by technical, economical, operational, aesthetical, and environmental considerations and may be the choice of either the owner, the contractor, the designer, or the user.

As a result, bridge construction builds a healthy competition as regards structural types, construction materials, construction methods, and other parameters that result in a polymorphy of bridges. In some aspects, bridges relect the technological development in a period or in a country. Among the different types of bridges, composite bridges have a signiicant place, because the combination of the most common construction materials, steel and reinforced concrete, allows the construction of safe, operational, durable, and robust bridges economically. Bridge design is strongly based on prescriptive normative rules regarding loads and their combinations, safety factors, material properties, analysis methods, required veriications, and other issues that are included in the codes. Composite bridges may be designed in accordance with the Eurocodes, which have recently been adopted across the European Union and many other countries worldwide. Eurocode 4, part 2 (EN 1994-2), is exclusively devoted to the design of composite bridges.

However, many Eurocodes and their different parts would need to be consulted as the design of bridges includes a variety of constructional issues and due to the fact that two construction materials are involved. This book presents in 13 chapters the main information needed for the design of composite bridges in accordance with the Eurocodes:

• Chapter 1 introduces the subject and provides a list of symbols used in the book.

• Chapter 2 presents the main types of common composite bridges. It discusses structural forms and structural systems, describes preliminary design aids and erection methods, and delves into the structural details.

• Chapter 3 summarizes the relevant design codes. These refer to actions, combinations of actions, safety factors, material properties, and limit state design.

• Chapter 4 discusses the actions to be considered, including trafic loads for road and railway bridges, temperature, wind, and earthquake, as well as the effects of shrinkage and creep of concrete.

• Chapter 5 introduces the limit states, presents safety factors for actions and resistances and factors for combinations of actions, and discusses durability issues.

• Chapter 6 presents the properties for structural materials used with reference to concrete, structural, reinforcing, and prestressing steel, as well as mechanical connectors, and provides criteria for their selection.

• Chapter 7 is devoted to modeling for global analysis. It presents alternative models for global analysis, shear lag effects, effects of rheological behavior, and cracking of concrete and models for slab analysis.

• Chapter 8 discusses the effects of plate buckling and deals with the critical and postcritical plate behavior and the column-buckling behavior of stiffened plated elements.

• Chapter 9 presents the veriications at ultimate limit states for members and cross sections with reference to various cross-sectional classes and for lateral torsional buckling.

• Chapter 10 refers to veriications at serviceability limit states, which include stress limitations, web breathing, control of cracking of concrete, delections, and vibrations.

• Chapter 11 lays down the rules for the shear connection between concrete and steel by means of headed studs.

• Chapter 12 presents fatigue analysis and design. It presents fatigue load models, detail categories, and fatigue veriications for structural steel, reinforcement, concrete, and shear connectors.

• Chapter 13 covers structural bearings and dampers, with an emphasis on reinforced elastomeric bearings. Covering all topics related to composite bridge design is a challenging task.

The authors have tried to provide as comprehensive a coverage as possible. Although not all types of bridges, for example, arch, cable-stayed, or suspension bridges, are fully covered and their substructures and foundations not addressed, the basic knowledge on steel structure is dealt with and topics related to analysis and design for the overwhelming majority of composite bridge superstructures are addressed.

The book is didactical and is addressed primarily to structural engineering students. However, it might also be helpful for bridge designers or practicing engineers who are converting from other codes to Eurocodes. For better understanding of the design procedures and the use of code provisions, several design examples are incorporated in the chapters.
