摘要
螺栓连接是角钢杆塔最为常用的节点形式.通过有限元计算,研究了受压时角钢螺栓节点的极限承载力,进而得到了螺栓节点受压时合理的减孔数.将有限元计算结果折算得到的减孔数与规范公式算得的减孔数进行了对比分析.分析结果表明,规范给出的减孔数的计算方法是偏于安全的.
Bolt connection is the most commonly used for angle steel tower joints.By the finite element calculation,this paper studies the ultimate bearing capacity of the angle steel bolt joints under compression load;then gets the reasonable number of hole reduction when bolt joints are under compression load.Through comparing the number of hole reduction calculated by the finite elements with that by specification's method;the regularity is found that the degree of safety calculated by the specification's method is generally on the safe side.
