A clear, comprehensive & practical guide to a core topic in civil/structural engineering which satisfies the textbook requirements of three years of study. It enables the student to obtain a thorough understanding of the techniques available to analyse and predict stress in any structure. It provides a clear explanation of theory applied to real structures/ practical situations and is well-supported by worked examples and problems throughout.
