Linear elastic iterative method for stability ultimate capacity of equal-leg angle towers.

ABSTRACT: An efficient linear elastic iterative method is proposed for the stability ultimate capacity of equal-leg angle towers, using an elastic modulus adjustment strategy in this paper. The angle steel stability generalized yield function (GYF) of AS/NZS4600 is selected, on which a precise homogeneous generalized yield function (HGYF) is developed through dimensionless analysis and regression. Based on the HGYF, the element bearing ratio is proposed as a dynamic threshold for distinguishing high-stress and low-stress elements in equal-leg angle elements. Then, an adaptive elastic modulus adjustment strategy is proposed for the linear elastic iterative analysis of the stability ultimate capacity of equal-leg angle towers. Compared to analytical solutions and traditional numerical methods, it can
