Comparison of the Bearing Capacity of LST- Profile Depending on the Thickness of its Elements

Abstract

The influence of local buckling on the bearing capacity of light steel thin-walled profiles is a hot topic today. In this paper we evaluated the effect of the thickness of the elements of the cross section on bearing capacity the profile in a transverse bending.

The problems of calculating the load-bearing structures made of light steel thin-walled profiles

“…Study of the bearing capacity, deformability and manufacturing technology of steel structures of cold-formed sections are devoted to [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. In [6,11,12] are considered the possibility of accounting the seventh degree of freedom in the creation of a thin-walled finite element.…”

Buckling Behavior of Cold-Formed Studs with Thermal Perforations

“…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.…”
