The 4th edition of the book has been thoroughly revised in consideration of the new version of DIN 1052 (2008 edition), the new standards for wood protection, and the fire protection standard DIN 4102-22. It provides a comprehensive overview, numerous design and construction examples, and a large number of explanatory illustrations. As a basis for legal decisions in the case of construction damages and accidents, the calculations according to the old standard are provided; however, the focus is on the new standard edition, which is based on Eurocode 5. The first volume covers the fundamentals of design, calculation, and execution of structures or components made of wood. New research findings, building authority approvals, and standards for timber construction have been taken into account. The book has become a classic in training and holds a firm place in professional practice.
