Using aspects of structural behaviour, good design practice and effective computational techniques to illustrate the importance of the fundamental theoretical concepts presented, this book provides a comprehensive introduction to the analysis and design of structures. The over-riding importance of equilibrium is emphasized and, together with related topics, is the subject of the first five chapters. After deflections have been introduced in chapter six, elastic theory, buckling, plastic theory and energy methods are all introduced and their range of applicability discussed. Numerous case studies are included to help readers gain an appreciation of how theory relates in practice to real life structures. With a broad range of worked examples, questions and references to further reading, Structures is the ideal course text for entry-level students on degree, HNC and HND courses.
