| Abstract: | In this paper, the step-reduction method for non-homogeneous linear dimension structures is applied to establish a numerical analysis model for steel tubular transmission towers, and a calculation method for integral stability is thus deduced. This calculation method, easy to implement with a computer, solves the problem of second-order calculation of the integral stability for complicated pole structures with load and rigidity varying along the poles, and it finds wide application in the engineering practi... |
