The fifth edition of this comprehensive textbook combines and develops concurrently, both classical and matrix-based methods of structural analysis. A new introductory chapter on structural analysis modelling has been added. The suitability of modelling structures as beams, plane or space frames and trusses, plane grids or assemblages of finite elements is discussed in this chapter, along with idealization of loads, anticipated deformations, sketching deflected shapes, and bending moment diagrams. With new solved examples and problems added, the book now has over 100 worked examples and more than 350 problems with answers. A new companion website contains computer programs that can serve as optional aids in studying and in engineering practice: www sponpress.com/civeng/support.htm . Structural Analysis: A Unified Classical and Matrix Approach , translated into six languages, is a textbook of great international renown, and is recommended by many civil and structural engineering lecturers to their students due to its clear and thorough style and content
