Steel plated structures are important in a variety of marine and land based applications, including ships, offshore platforms, box girder bridges and box girder cranes. During their life time, the structures constructed using these members are subjected to various types of loading which is for the most part operational, but may in some cases be extreme or even accidental. It has been well recognized that the limit state design approach is better than the traditional allowable stress design approach since the former makes possible a more rigorously designed, yet more economical structure considering the various relevant modes of failure possible.

This book reviews and describes both fundamentals and practical design procedures for the ultimate limit states of steel plated structures. The computer programs, which automate the more advanced and sophisticated design methodologies presented in this book, are provided. While the book consists of 14 chapters and appendices, it is designed as a textbook so that 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.

Chapter 1 presents design principles based on limit states, which can be classified into four types, namely serviceability limit state, ultimate limit state, fatigue limit state and accidental limit state. Corrosion damage model for aging steel structures is also presented in Chapter 1.

Chapter 2 describes buckling and ultimate strength formulations of stiffeners together with attached plating.

Chapter 3 presents elastic and inelastic buckling strength formulations of steel plates under complex circumstances which include load combination, elastically restrained edges (as well as simply supported or fixed conditions), residual stresses and perforations.

Chapter 4 presents post-buckling and ultimate strength formulations of steel plates which takes into account the effects of fabrication related initial imperfections, perforations and corrosion damage.

Chapter 5 presents elastic and inelastic buckling strength of stiffened panels and grillages under combined loads as well as under single types of loads.

Chapter 6 presents post-buckling and ultimate strength formulations of stiffened panels and grillages under combined loads, which take into account the influence of fabrication related initial imperfections.

Chapter 7 presents ultimate strength formulations of plate assemblies such as plate girders, box columns, box girders and corrugated panels.

Chapter 8 presents ultimate strength formulations of ship hulls.

Chapter 9 deals with structural impact mechanics and structural design formulations for accidents such as collision and grounding.

Chapter 10 presents fracture mechanics and residual strength assessment of steel plated structures with existing crack damages and under monotonic extreme loads.

Chapter 11 presents a semi-analytical method for analysis of elastic-plastic large deflection behavior of steel or aluminum plates under combined loads taking into account the influence of fabrication related initial imperfections.

Chapter 12 presents the theory of the nonlinear finite element method simplified on the basis of the plastic node method.

Chapter 13 presents the idealized structural unit method (ISUM) which has now been widely recognized by researchers as an efficient and accurate methodology to perform nonlinear analysis of large plated structures such as ships, offshore platforms, box girder bridges or other steel structures.

Chapter 14 presents some practice problems for each chapter and solutions to selected problems. Finally, Appendices present how to download the computer programs introduced in this book.

The present book is primarily based on the two authors' own insights and developments obtained over more than a total of 50 years of professional experience, as well as existing information and findings by numerous other researchers and limit state practitioners. The intention behind writing this book is to develop a textbook and handy source to the principles of limit state design of steel plated structures. This book has been designed to be well suited to the university students who would be approaching the limit state design technology of steel plated structures perhaps for the first time. In terms of more advanced and sophisticated design methodologies being presented, the book should also meet the needs of structural designers or researchers who are involved in the field of naval architecture, offshore, civil, architectural and mechanical engineering. Hence, apart from its value as a ready reference and an aid to continuing education for the established practitioners, this book can be used as a textbook in teaching courses on limit state design of steel structures at the university level. The reader should be able to obtain an insight into a wider spectrum of limit state design considerations in both an academic and a practical sense.
