The fundamentals of structural engineering are still traditionally traced back to bar statics. This textbook aims to awaken an understanding of the complex interrelationships involved. It is designed to provide the reader with a solid foundational knowledge to calculate structures in practice with the support of data processing and to assess the results. Bar statics is explained in this book with numerous examples, just as it is applied in teaching. The book is recommended for every student for exam preparation and to refresh the material learned.
