An Introduction to Structural Mechanics aims to teach the fundamental principles of structures via simple explanations of the theory and numerous worked examples. The emphasis throughout is on problem-based learning. The worked examples start from a fundamental level and progress to more difficult, intricate and taxing problems. Early examples assume little or no experience in the subject matter, but soon propel the reader forward to solving complex, practically-based structural systems. Further problem - with solutions - aim to further bolster learning at the end of each chapter. The book will provide a powerful learning or revision tool for undergraduate civil engineering or building students.
