The book contains data on the operation of all types of masonry made of artificial and natural stones in the structures of structures. Based on the experiments of research institutes of the USSR, USA and Germany, the mechanical properties of stones and solutions were studied, on which the strength and elastic properties of masonry depend, and laws were established in the field of strength and stability of elements of stone structures, which formed the basis of GU and N for calculating stone structures. The book is intended for design engineers, research workers, teachers of technical colleges and students who work in depth in the field of stone structures.
