An experimental investigation was made of the inelastic buckling of axially loaded, pinned end single angle, tee, and double angle struts. A total of 54 struts with modified slenderness ranging from 0.33 to 1.08 was tested. Specially designed pinned end supports allowed the end cross sections to rotate about the major and minor axes, but restrained them against twisting about the longitudinal axis. All struts failed in the inelastic range by excessive bending and twisting. The experimental results compared with the theoretical predictions and with other test results. It was found the related design rules in the current Australian as 1250-1981 and American AISC specification are satisfactory for single and double angle struts, but are slightly unsafe for tee struts. Experimental results are compared with the SSRC multiple column curves. It is recommended that curve 2 be adopted for single and double angle struts and curve 3 for tee struts. (Author/TRRL)
