【Abstract】 This paper introduces the solution of the lateral buckling of a simply supported beam with the narrow rectangular cross-section.It also explains the calculating of the critical load that the bar has varied from the linear cross-sections along the longitudinal axis.The result of using the method of the infinite series shows that is valuable theoretically and practically.更多还原
