Abstract

The invention provides a calculation method and device for the compression bearing capacity of a K joint diagonal member. The calculation method comprises the steps that the slenderness ratio lambda<1> of the K joint diagonal member is determined; the slenderness ratio lambda<1> of the K joint diagonal member is corrected, and the corrected slenderness ratio lambda<2> is obtained; the stability coefficient phi of the diagonal member is determined according to the corrected slenderness ratio lambda<2>; the axis pressure design value, the gross section area and the stability strength reduction coefficient of the diagonal member are obtained; and the compression bearing capacity of the diagonal member is determined according to the stability coefficient, the axis pressure design value, the gross section area and the stability strength reduction coefficient of the diagonal member. According to the calculation method and device for the compression bearing capacity of the K joint diagonal member, the slenderness ratio lambda<2> of the K joint diagonal member is corrected, and the compression bearing capacity f of the K joint diagonal member is determined according to the corrected slenderness ratio; and compared with the prior art, the deviation between the K joint diagonal member bearing capacity calculated through the method and the actual situation is small, the calculation method is simple, convenient and feasible, and a basis can be provided for design and calculation of the K joint diagonal member arranged in a parallel axis mode, so that reducing of the weight of a pole tower and optimizing of the overall stress of the pole tower are facilitated.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation engineering, in particular to a method and device for calculating the compressive bearing capacity of a K-node oblique material. Background technique [0002] The production and transmission of electric energy is the lifeblood of the country's economic and social development, and the transmission line is the "lifeline" related to the national economy and people's livelihood. High-voltage, large-capacity, and long-distance power transmission is the focus of power grid construction. In order to meet this development requirement, new power transmission technologies such as multi-split, large-section conductors, multiple circuits on the same tower, and UHV have been widely used. The height of towers keeps increasing. Generally speaking, towers over 60m can be called tall towers. Due to the increasing importance of lines, the requirements for the safety performance of tall...
