The Q420 angle of L220X20 axial compression test is carried out, and make a theoretical analysis is made on this basis. Combined with the finite element, analysis is made on the angle of the large size parameters, which is compared with the columns curve of the current steel design code. The results showed that: the columns curve of the large-size high-strength edge angle is higher than the current "design code of steel structures" class section column curve, in general between a class between the curve and b-type cross-section columns. The b-class columns curve of current "design code of steel structures" can apply to the high-strength side angle. Source

The members with combined angle iron cross-section are widely used in electric transmission towers and the behavior is complex. In this study, the finite element analysis were conducted to study the compressive behavior of members with combined angle iron cross-section, and adjusted across experiments in the paper. On the basis, the influence of filled plate is studied on the ways of numbers, arrangement, shapes and the connection mode. Finally, theoretical formulas are provided for engineering design. Source
