Abstract

An analysis of the use of metal structures in modern construction and considered the possibility of improving them for widespread use not only in industrial, civil, commercial, but also residential construction.

High performance characteristics, high strength and homogeneity of the metal structure explain its demand in the field of construction.

The steel framework allows to increase considerably functionality of the building and to reduce terms of its construction. In comparison with various modern materials, each steel structure has key and undeniable advantages - a high degree of factory readiness, full maintainability and reusability.

Rolled steel is increasingly used, and its range, as well as the physical and chemical properties of alloys are constantly improving. At the same time, due to their versatility in processing, strength, maintainability, reliability in operation and industry of steels, their application solves numerous problems of residential, commercial and industrial construction.

Alloys with new alloying components allow: to create light steel and thin-walled structures with the increased bearing capacity; to conduct cheap construction of small and high-rise buildings and structures; to improve the architectural appearance of buildings; ensure high rates of production.

Metal is becoming a formative factor in architecture, especially in new types of buildings - modern exhibition and sports complexes, railway stations, shopping malls, stadiums, not to mention the transport, industrial and civil construction. Metal is a specific means of architectural development of space.

Given the ratio of strength and density, steel is considered a lightweight building material. In comparison with a tree this factor at it is lower twice, in comparison with concrete - in 8 ... 10 times and in comparison with a brick - in 18 ... 20 times. Accordingly, buildings and structures with a steel frame can be erected on pile, tile and strip foundations of lightweight construction. (Review article)
