Buckling behavior of cold-formed studs with thermal perforationsGarifullin, Marsel (Avtor) Sinelnikov, Alexey (Avtor) Bronzova, Maria (Avtor) Kovačič, Boštjan (Avtor) Kamnik, Rok (Avtor) structural engineeringsteel structurescomputer simulationsnonlinear modelStudies have shown that the optimal structural scheme for low-rise buildings that meets all regulatory requirements is a frame system. In this connection, thin-walled cold-formed steel (CFS) profiles seem to be the best material for constructing light steel framed (LSF) walls. The framework of LSF walls is usually constructed from CFS C-shaped profiles. To increase the thermal effectiveness of a wall, CFS profiles usually have thermal perforations and thus are called thermoprofiles. However, these openings have a negative impact on bearing capacity of profiles and require accurate evaluation. In this article a relatively new reticular-stretched thermoprofile with diamond-shaped openings is considered. The article deals with the buckling analysis of perforated CFS C-sections subjected to compression.20162016-08-29 15:31:47Znanstveno delo62553sl
