Reviews and describes both the fundamental and practical design procedures for the ultimate limit state design of ductile steel plated structures
The new edition of this well-established reference reviews and describes both fundamentals and practical design procedures for steel plated structures. The derivation of the basic mathematical expressions is presented together with a thorough discussion of the assumptions and the validity of the underlying expressions and solution methods.
Furthermore, this book is also an easily accessed design tool, which facilitates learning by applying the concepts of the limit states for practice using a set of computer programs, which can be downloaded.
Ultimate Limit State Design of Steel Plated Structures provides expert guidance on mechanical model test results as well as nonlinear finite element solutions, sophisticated design methodologies useful for practitioners in industries or research institutions, and selected methods for accurate and efficient analyses of nonlinear behavior of steel plated structures both up to and after the ultimate strength is reached.
Covers recent advances and developments in the field
Includes new topics on constitutive equations of steels, test database associated with low/elevated temperature, and strain rates
Includes a new chapter on a semi-analytical method
Supported by a companion website with illustrative example data sheets
Provides results for existing mechanical model tests
Offers a thorough discussion of assumptions and the validity of underlying expressions and solution methods
Designed as both a textbook and a handy reference, Ultimate Limit State Design of Steel Plated Structures, Second Edition is well suited to teachers and university students who are approaching the limit state design technology of steel plated structures for the first time. It also meets the needs of structural designers or researchers who are involved in civil, marine, and mechanical engineering as well as offshore engineering and naval architecture.

Klappentext
Plated structures are important in a variety of marine, land-based and aerospace applications, including ships, offshore platforms, box girder bridges, power/chemical plants, box girder cranes, and aircrafts. The basic strength members in plated structures include support members (such as stiffeners, girders and frames), plates, stiffened panels, grillages, box columns, and box girders. During their lifetime, the structures constructed with these members are subjected to various types of action and action effects that are usually normal but sometimes extreme or even accidental. It is now well recognized that the limit state approach is a much better basis for structural design than allowable working stresses and simplified buckling checks for structural components. This book reviews and describes both the fundamentals and practical procedures for the ultimate limit state analysis and design of steel- and aluminum-plated structures. Structural fracture mechanics and structural impact mechanics are also described. This book is an extensive update of the first edition Ultimate Limit State Design of Steel-Plated Structures, published in 2003. Particularly valuable coverage in this book includes:
