摘要: Abstract The lateral buckling analysis of cold-formed thin walled beams subjected to pure bending moments has been performed. critical loads are estimated based an optimization criteria. stresses compared with the published results, they show excellent agreement. effect beam length, radius and thickness flanges length extended open flanges, on have studied for several combinations geometric parameters beam. Among three beams, found be maximum. However, considering material manufacturing costs, rounded cross section efficient in resisting loads.
