This thesis presents an analytical and experimental assessment of the behavior of circular steel hollow sections under bending. Three dimensional non-linear finite element models have been established by ANSYS11 Finite element program to assess the allowable bending strength and D/t limits which separate between the sections types (compact, non-compact, slender). Several parameters are studied; Diameter to thickness (D/t) ratio, length to diameter (L/D) ratio, load conditions, boundary conditions, and variation of steel profile. Nine full-scale circular beams were tested to verify the finite element models; seven specimens were tested in cantilever models and two specimens were tested in simple beam with two concentrated loads. An analytical equation was proposed to predict the allowable bending stress in circular steel tubes. The equation was verified by a parametric study
