Successful construction requires not only knowledge of material properties and corrosion and fire behavior but also a solid understanding of statics and strength theory, along with thorough training in the essential construction principles of this specific building method. This book focuses on these construction principles and provides the necessary foundational knowledge. It covers the most important design and calculation rules for solid wall beams, truss beams, trusses, crane tracks, frame structures, and load-bearing elements with thin-walled cross-sections. In addition to detailed graphical documentation of the constructions, the associated proofs are presented in a clear and comprehensive manner through numerous calculation examples. The basis for all calculations now includes the new German (DIN 18800-1 to -2) and European standards (EC 3).
