The book, deals with the steel structures according to European Standards: EC0, EC1, EC3; and with introductory references to U.S. Standards: IBC, ASCE 7, and AISC. The ultimate goal of the book is that the appropriate organizations soon come to agreement on a political and scientific basis in order to adopt one set of design standards for use around the world. The rigorous theoretical discussion is enhanced with practical applications and exercises that help understanding and expand the theory for use by the practicing engineer or student. The topics covered in are divided into five chapters, and includes six useful appendixes as well. The chapters included are: Chapter 1: Materials; Chapter 2: Limit state design; Chapter 3: Connections; Chapter 4: Trusses and Bracing; Chapter 5: Beams. The book is aimed at both the student of structural and civil engineering as well as the practicing professional engineer. It can be used as a supporting book in courses on structural design, or used as a reference for design engineers.
