Web Middle Of The V-shaped Stiffening Crimp Channel Column A Single Wave And Multi-wave-related Buckling Performance Analysis And Testing Research

The single-wave & multiple-wave interactive buckling theory and tests in thin-walledlipped-channel beam-columns with web's intermediate V-stiffeners are presented. Theanalysis is divided into three part: 1) A complex finite strip method using bubble function ispresented for determining the single-wave bucking of thin-walled members. 2)A complexfinite strip method using bubble function is presented for determining the single-wavepost-buckling of thin-walled members. 3) A complex finite strip Garlerkin variationalmethod using bubble function is presented for determing the multiple-wave interactivebuckling of thin-walled members. Tests on 15 stubs and 6 columns were performed. Theexperimental results are in good agreement the numerical analysis.
