“…The lightweight steel thin-walled structures (LSTS) use in Russia is hampered by the absence of an appropriate regulatory framework. The existing regulatory documents cannot be applied, because they do not take into account the local stability in the early stages of loading loss possibility factor of LSTS [27].…”

Lightweight steel concrete structures (LSCS) - an innovative building structure type that can be used both as load-bearing and as enclosing one. They consist of profiled steel usually galvanized and cold-bent - filled with a monolithic foam concrete with a 200kg/m3 density, and with fiber cement sheets sheathing. These structures can be used in industrial and civil buildings as internal and external bearing and enclosing wall structures, and as slabs. According to the LSCS production method, prefabricated panels (walls and slabs) and building site performed constructions are distinguished. The article presents the LSCS subspecies, representing slabs panels made of galvanized profiled steel, density medium grade D400 monolithic foam concrete and sheets “Steklotsem” sheathing, bearing capacity experimental studies results. The paper confirms that such panels can be used in civil buildings and withstand the appropriate load, regulated by the current codes and rules. Moreover, it has been experimentally proved that the foam concrete, despite its own extremely low strength class, actually includes in the operation, preventing such effects as stability local loss, crushing and profile steel elements cross-section warping and increases the slabs overall load capacity by 20-25%.

Cold formed steel members with edge stiffened holes are a new generation of cold formed members recently developed by the building industry. Very little research has been performed on such sections to determine their local and distortional buckling capacity. This article provides the numerical results of elastic local buckling analysis of cold-formed lipped channels with edge stiffened holes. For flexural elements values of critical buckling moments are calculated and the influence of hole spacing and diameter on elastic buckling capacity is determined.

“…Sinelnikov [36][37][38] and Nazmeeva [39,40] investigated the buckling behavior of compressed cold-formed columns made of RST-profiles. Trubina [41][42][43][44] analyzed the problem of local and global buckling of RST-profiles in bending. Despite the growing interest to RST-profiles, the influence of perforations on the resistance of profiles remains an open issue.…”

Abstract. Studies have shown that the optimal structural scheme for lowrise 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.
