The first part of the three-volume series presents the analysis of statically determinate beam structures, particularly the determination of their support and internal forces. Numerous examples demonstrate the effectiveness of equilibrium considerations and the section method, often illustrated with the elementary structures of single-span beams and single-span beams with cantilevers. Additionally, truss beams are covered. The completely revised book aims to explain the techniques for problem-solving in an easily understandable manner and to familiarize the reader with the important tools required for this. The excellent didactics and problem-oriented structure of the book lead to rapid learning success in preparation for exams.
