Due to the relatively large slenderness of plated structures, the proof of adequate buckling resistance is crucial for dimensioning. Plate buckling is a stability problem of a compression-loaded plate and is generally characterized by failure of the structure prior to achieving plastic component resistance. The stability verification of welded plated structures assisted by finite element analysis (FEM) is becoming increasingly prevalent in applied engineering. The rules and examples given in this book might illustrate the correct application of the numerical models and give background information on the FEM-based design of welded plated structures.

The recently completed European research program OUTBURST – Optimal and aesthetic design of curved steel bridges (RFCS Nº 709782), where the authors of this report were involved, significantly supported the development of new design rules for curved steel plates. In the frame of this research, several individual curved panels and two bridge prototypes were tested. Physical and geometrical numerical nonlinear analysis were performed to recalculate the tests and validate numerical models. The results of the nonlinear analysis were used in numerical parametric studies.

The book deals with the seismic design of steel structures based on EN 1998-1 (2004). It contains the essentials of theoretical background of seismic engineering, design requirements and detailing rules for building applications.
Calculation examples are included in the relevant chapters in order to provide a better understanding to the Reader. In addition, the book provides insights about the design assisted by testing as well as some design examples of real buildings:

A detailed classification of shear connections in this document is based on their shear-slip properties, which allows for consideration of hardening, plastic and softening connection types. A theory developed for slip deformations is applicable for both full and partial shear connections. The connection stiffness parameters make it possible to estimate the maximum slips in both serviceability and inelastic states of stresses. With the aid of parameters developed, it is also possible to study the effects of quasi-static and fatigue loading on the bending stiffness of composite beams where the stud shear connection is deteriorating due to load cycling.

The majority of fatigue damage cases that have been reported for steel and composite bridges were generated by “secondary” effects that were unforeseen or overlooked in the design of these structures. These effects are often the result of improper detailing and inadequate idealization of the behaviour of steel bridge details.
This volume presents a catalogue of more than 100 fatigue damage cases in steel and composite bridges. These cases are categorised based on detail type and the mechanisms behind fatigue damage are presented and discussed.
