摘要： 为有效提高结构承载性能,在输电塔单肢角钢主材的下部采用组合双角钢的方法,依托输电线路实际工程,选取输电塔中5个典型的单双角钢过渡节点,利用ABAQUS软件建立精细化有限元模型,通过数值模拟分析过渡节点的传力机理和承载力特性,开展不同偏心距的过渡节点受力分析,提出考虑弯矩调整系数和弯矩强化系数为主要控制参数的水平板厚度计算公式。

Abstract: The adoption of combined double angle steel in the lower part of single angle steel as the main material was a common method to effectively improve the bearing performance of the transmission tower, which was conducive to clarifying the force transmission path between variable sections while ensuring high material utilization. However, there were still lack of systematic research and blank in the calculation codes for such joints. Consequently, based on the actual project, 5 typical single-double angle steel joints were selected and modelled in ABAQUS software. The bearing capacity characteristics and force transmission mechanism of the joints were analyzed through numerical simulation. Considering that the bending moment was the main factor affecting the performance of the horizontal plate, different single-double angle steel joints were simulated by changing the eccentricity. The bending moment adjustment factor and the bending moment enhancement factor were raised as the main control parameters in the horizontal plate thickness calculation formula.

Key words: single-double angle steel joints, horizontal plate, transmission tower, numerical simulation, bearing capacity
