- Abstract:
- T-struts subject to centroid compression buckle flexural-torsionally about their axis of symmetry.When the foree is applied at the shear center of the section,T-struts buckle either flexurally or torsionallywithout coupling of flexure with twisting.Although the buckling load about the symmetry-axis of shear centerloading is greater than that of centroid loading，the design capacity of T-struts with defect such as fabricationerror, load eccentricity and residual stress decrease by shifting the working line of a T-section compressionchord to the shear center. This article presents the equivalent slenderness ratio method,a new method for thedesign of ’T-struts subject to compressive force,introduces another three methods including the one presentedby Chen Shaofan,the one in code and the one in ANSYS,contrasts the calculation results of those four meth-ods and recommends the implementation of equivalent slenderness ratio method in the design of T-struts subjectto compressive force.
