Structural Mechanics is an important course in the discipline of civil engineering. This book is intended primarily as a textbook for undergraduate and firstyear graduate courses of Structural Mechanics for civil engineers.

This book is based on the development and progress of structural mechanics course teaching in Tongji University during recent years: be themed with the basic concepts of mechanics and their rational applications, originated from the cognitive rules of the objective world, supported by engineering practice background, and aimed mainly at improving students’ qualities and abilities. It also reflects the development features and needs of the times of structural mechanics.

This book consists of 12 chapters. Chapters 1 to 5 mainly deal with analysis of statically determinate structures, including geometric construction, internal force and deformation, and influence line analysis. Chapters 6 to 9 deal with analysis of statically indeterminate structures, including force method, displacement method, matrix displacement method, practical and conceptual methods. Chapters 10, 11 and 12 deal with analysis of dynamics, stability and ultimate load problems, respectively.

This book can serve as a textbook for Structural Mechanics in the areas of civil engineering, transportation engineering, hydraulic engineering, mechanical engineering and mechanics, etc., and as a reference book for engineers and scientists in the relevant fields.
