Abstract. The development and improvement of metal building structures is closely related to solving such tasks as reducing metal consumption, increasing labor productivity in the manufacture and installation of structures, increasing the speed of construction of buildings and structures, and significantly reducing the cost of steel structures. The effective achievement of these goals is due to the integrated consideration of the factors of scientific and technological progress in two main areas. Firstly, the development of the theory of shaping the bearing elements of building structures of capital construction facilities, which serves as the basis for minimizing material consumption and cost. Secondly, there are successes in related industries: metallurgy, which provides the production of efficient types of steel, welding, and mechanical engineering, which creates equipment for processing and installation. The modern development of metal structures is characterized by the active introduction of thin-walled elements, including welded I-beams with a thin corrugated wall. At the same time, the corrugation of the wall significantly increases its stability, which reduces the metal consumption and weight of the structure. The use of thin-walled elements highlights the problems associated with ensuring local stability and corrosion resistance. However, practical research demonstrates that these problems are successfully solved using innovative design methods and modern production technologies.
