Abstract. Steel beams with sinusoidal corrugated webs are known since the middle of the last century. Their bearing capacity is widely studied, the design rules of these beams are included in the existing regulations, such as "Standards European Committee for Standardisation (CEN): DIN EN 1993:2007-02, Eurocode 3: Bemessung und Konstruktion von Stahlbauten - Teil 1-5: Aus Blechen zusammengesetzte Bauteile", SNiP RK 5.04-23-2002 "Steel Structures. Design Standards." and SP 16.13330.2017 "SNiP II-23-81* Steel Structures". However, there is still an open question about the bearing capacity of sinusoidal corrugated webs of beams with holes bordered with steel sleeves to ensure the stability of the wall. In this paper, a method for calculating beams with sinusoidal corrugated webs, weakened by round and square holes, which are bordered by pipes is proposed. To develop this method of calculation a numerical experiment was conducted. A number of finite element models of such beams with varying web thickness, beam length, diameter and hole location were created and analyzed using the finite element method. ABAQUS computer complex was used for calculations. The result of the research conducted is a technique that makes it possible to determine the bearing capacity of sinusoidal corrugated webs of beams with round and square holes, bordered by pipes. To confirm the theoretical calculations, full-scale tests were carried out.
Key words: steel beams with sinusoidal corrugated webs, mathematical models, finite elements method.
