Flexural-Torsional buckling tests of cold-formed lipped Channel beams under restrained boundary conditions
Abstract In this paper, tests on flexural buckling (Lateral-Torsional) of cold-formed steel (CFS) lipped Channel beams under restrained boundary conditions are described. Two point loading for flexural tests have been established for 3.0 m span to obtain uniform bending moment. The section sizes selected for testing are 100×50×10, 100×50×15, and 100×50×20 mm with 1.6 and 2.0 mm thickness for the investigation. Carefully designed loading and support systems were used in the tests to apply gravity load through the web of the section and to ensure that simply supported ends were established. The test results were compared with the moment obtained using BS5950: Part 5 and IS code 801-1975. The influences of warping and torsional restraints on flexural capacity are presented. The influence of buckling length for different boundary conditions proposed by Rhodes is considered to calculate critical flexural-torsional buckling moment.
