[再版前言]

現(xiàn)代船舶結(jié)構(gòu)設(shè)計(jì)(Modern Ship Structural Design)是上海交通大學(xué)國(guó)家一級(jí)重點(diǎn)學(xué)科“船舶與海洋工程”學(xué)科一門(mén)重要的研究生專業(yè)課程。從2004年至今，筆者已在上海交通大學(xué)主講本課程15學(xué)期,為配合該課程的教學(xué)工作,筆者于2013年編寫(xiě)了《船舶結(jié)構(gòu)設(shè)計(jì)與分析》的英文版教材。該教材出版以來(lái)，聽(tīng)課的研究生在課堂學(xué)習(xí)中對(duì)本教材提出了一些中肯的改進(jìn)意見(jiàn)，恰逢上海交通大學(xué)在2019年立項(xiàng)了“雙一流”研究生優(yōu)質(zhì)課程建設(shè)項(xiàng)目，這都為該教材的再次出版提供了支持和幫助。

在第二版的修訂調(diào)整過(guò)程中，本教材增加了下列新內(nèi)容: (1) 講述了下列各型散貨船的結(jié)構(gòu)要素和船型特點(diǎn): 卡姆薩型散貨船、紐卡斯?fàn)栃蜕⒇涊�、瀨戶型散貨船、圣勞倫斯型散貨船、馬六甲型散貨船和敦刻爾克型散貨船。(2) 講述了散貨船艙口處的船體應(yīng)力集中現(xiàn)象和局部加強(qiáng)措施，引用了國(guó)際船級(jí)社聯(lián)合會(huì)有關(guān)艙口蓋強(qiáng)度衡準(zhǔn)的統(tǒng)一要求，即將艙口蓋上承受的海水壓力按一干舷和航速的函數(shù)來(lái)計(jì)算。(3) 講述了散貨船艙底淤泥隨船舶搖蕩而產(chǎn)生的自由面現(xiàn)象及其控制措施。(4) 講述了集裝箱船為了滿足《國(guó)際海上人命安全公約》的可視性要求而將橋樓結(jié)構(gòu)前移的新設(shè)計(jì)方案，等等。

本書(shū)可用作船舶與海洋工程及土木工程專業(yè)本科生和研究生的專業(yè)教材，也可用作船舶結(jié)構(gòu)工程師和船舶總體設(shè)計(jì)師的參考資料。同時(shí)本書(shū)的相關(guān)內(nèi)容對(duì)從事結(jié)構(gòu)設(shè)計(jì)的土木工程師和機(jī)械工程師也大有裨益。

在重新編寫(xiě)本教材的過(guò)程中，筆者有幸得到了上海交通大學(xué)船舶海洋與建筑工程學(xué)院主管研究生教學(xué)工作的院領(lǐng)導(dǎo)和上海交通大學(xué)出版社各位責(zé)任編輯的大力支持和幫助，筆者對(duì)此表示衷心的感謝。

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).
