The reference work of a generation in construction and education at universities. The reprint now makes this significant - still relevant - work available again: The book includes both published volumes. In Part 1: among other things, principles and structures of lightweight construction, thin-walled isotropic surfaces and skin fields, thin-walled profile bars, anisotropic surfaces, sandwich panels. In Part 2: among other things, criteria and methods for designing and optimizing, selection and load-appropriate design of components and structures, based on current construction methods and materials, with a focus on reliability and damage tolerance.
