The material in this book has been continuously developed and improved since the author started to teach the course of Modern Ship Structural Design in the Department of Naval Architecture and Ocean Engineering of Shanghai Jiao Tong University SJTU in 2004. The subject of marine structural design and analysis is so broad that it is not possible to incorporate every aspect of this subject in one textbook. No attempt has been made to make the presentation complete in this book. However, the topics included in the book have been made as complete as possible so that they can be studied in their entirety without reference to other works. Most of the basic ideas of the subjects covered have been included. The book is intended to have at least two applications. It is expected that the book may be used as a textbook in both the undergraduate and graduate studies for students majoring in the areas of Naval Architecture, Ocean and Civil Engineering. On the other hand, the final results including handy tables and illustrations, may be referenced directly without going through detailed derivation. Therefore, the book should also be useful to the marine structural engineers and naval architects, as well as civil engineers and mechanical engineers who work on structural design.
Briefly, the organization of this book is as follows： Chapter 1 is an introduction to marine structural design including explanation of both the traditional design method and the modern design method. Chapter 2 outlines some marine structural design fundamentals including structural arrangements, structural materials, welding and some basic knowledge on classification societies and their rules. Chapter 3 and Chapter 4 consider loads and loads combinations in the process of marine structural design and how to calculate initial scantlings for a specific marine structure. Chapter 5 deals with the total strength assessment of an initially designed marine structure. Yielding, buckling and fatigue criteria are outlined in this chapter. Detailed explanations regarding spectral fatigue analysis of ship structures are also given in this chapter. Finally, Chapter 6 presents some fundamental knowledge about marine structural design optimization and several calculation examples. A knowledge of calculus, principles of naval architecture, strength of materials, solid mechanics and numerical optimization is the prerequisite for the complete use of this book.
It is my pleasure to acknowledge the help I received during the preparation of the first edition of this book. Among my students, my special thanks are due to Shi Yongpeng and He Yong, who ably assisted in a number of computations, and Zhang Youwen, who unfailingly assisted in putting the manuscript in proper order. The first edition of this book was published in 2013 and has since been successfully utilized as a textbook in my graduate course teaching in the Department of Naval Architecture and Ocean Engineering in SJTU. I am also grateful for those who have reviewed my application proposal for publishing the second edition of this book. Among my colleagues at the School of Naval Architecture, Ocean and Civil Engineering of SJTU, I am deeply indebted to the school vice dean for giving me strong support to finish writing this book. While it has been a joy to write this book, only the enjoyment and benefits realized by the readers will make my labor fruitful.
It is mentioned that during my utilization of the first edition of this book in my graduate course teaching in SJTU, I have received many valuable suggestions from my students in my class regarding how to continually improve the quality of the book. It was therefore envisioned that the publication of a second edition of this book including these valuable suggestions would be very much beneficial to the future students who would learn from the book. Through keen competition, this author won the funding for publishing this second edition book in 2019 from the Double First Class initiative in China. This generous funding, the author meticulous attention to the writing details and the book reviewers constructive comments all have contributed to the successful publication of this second edition.
A final suggestion to the future educators instructing marine structural design and analysis courses is to utilize this book in combination with the following supplement materials：
ABS American Bureau of Shipping Rules for Building and Classing Steel Vessels, Part 3, Hull Construction and Equipment; ABS Rules for Building and Classing Steel Vessels, Part 5C, Specific Vessel Types Chapters 16; ABS Rules for Building and Classing Steel Vessels, Part 5C, Specific Vessel Types Chapters 713.
