M. : Stroyizdat, 1975. — 80 s . The characteristic of modern domestic and foreign construction steels of high and high strength is given, the reduction in the mass of structures when using these steels is considered. The influence of technological properties of high-strength steels on operation modes and equipment in the manufacture and installation of structures is shown . Indicators of labor intensity, cost and investment for construction are substantiated. The methodology and algorithm for choosing the optimal steel class based on the relative costs and shows the areas of rational use of perspective steels in metal structures are given. The book is intended for engineering and scientific workers of design and research organizations, and can also be useful to specialists in the manufacture and installation of structures.
