Abstract:
Ultimate bearing capacity of single angle struts with one-sided bolt connection was studied by combining with the finite element simulation according to results of strut tests with 70 angles. The relationship between failure mode and slenderness ratio was discussed. The construction measures to increasing bearing capacity of this kind of members were also proposed. Based on the comparison of several relevant codes, revising suggestions for calculation formula of strut stability in Technical Regulation of Design for Tower and Pole Structures of Overhead Transmission Line(DL/T 5154—2002)were put forward. The analytical results show that failure of members with low slenderness ratio tends to cause local buckling, while failure of members with high slenderness ratio will cause flexural buckling. It is also pointed that different formulas for calculating equivalent slenderness ratio should be adopted respectively for members buckling towards parallel axis and those towards minor axis. Research results can provide theoretical basis for design of steel towers in the future.
