Functional and Economic Aspects of Steels for Metal Structures

The quality of structural steels currently available is discussed. Their characteristics are regulated by new standards for steel and iron structural components and in design standards. Such components include beams, pipes, and rolled components for use in buildings, bridges, and other structures. The maintenance of high performance in high-strength steels is considered. The feasibility of decreasing factors such as the cost of metal structures and the manufacturing complexity is discussed. The excellent cold strength of current steels permits improvement in the operational reliability of structures, especially in the severe climatic conditions encountered in Siberia and in the Arctic.
