摘要
在国外 ,不等边角钢已广泛应用于输电线路铁塔。而目前国内对不等边角钢受力状态和特性 ,不同的杆件端部连接方式对其承载力的影响 ,杆端偏心对节点强度的影响等的理论分析与试验研究才刚刚起步。从“不等边角钢用于输电杆塔的试验研究” ,初步摸清了不等边角钢杆件和节点构造的受力特性 ,提出了相应的设计和选材参数 。
The non-equilateral angle steel has been widely used in transmission towers abroad.While in China it is just a beginning for theoretic analysis,test and study on force applied status and property of the non-equilateral angle steel,effect of end connection method of different members on their bearing force,effect of eccentricity of member end on the strength of nodes,etc.From Test and study on non-equilateral angle steel applied in transmission towers the author has understood the forced applied properties of non-equilateral angle steel members and node structure,put forward the corresponding parameters for design and material selection.It has offered reliable design reference criteria for application of non-equilateral angle steel components in transmission towers.
