Objective In order to research the elastic buckling of thin-walled members Methods A code based on transfer finite-strip method(TFSM)was compiled according to the relevant theory of finite strip transfer matrix method.The elastic buckling analysis of thin-walled members was carried out by importing into the corresponding section parameters and material parameters,which greatly improved the calculation efficiency.Results In order to verify the feasibility of the program,firstly,the buckling analysis of thin-plate members with different strip ele-ment numbers was carried out,and the calculation results were compared with the theoretical values to investigate the influence of different strip element numbers on the calculation accuracy.Then,the elastic distortional buckling of cold-formed thin-walled steel members was analyzed by adopting the strip element division method with high precision and compared with the calculation results of finite element method and classical finite strip method.Conclusion The TFSM can be applied to the elastic buckling analysis of cold-formed thin-walled members.
