| 摘 要： | 大型输电铁塔广泛应用钢管节点,为了简化制作安装,避免复杂的相贯线切割,塔身斜材与主材的连接经常将钢管开长槽孔和插入的钢板焊接.由于钢管截面只是部分和钢板连接,在拉力作用下,管板节点易发生剪切滞后破坏.为研究剪切滞后对管板节点受拉极限承载力的影响,进行了一系列分析,并将研究结果和现行设计规范公式进行了比较.

| Abstract: | The tubular joints are wildly used in transmission towers.Because tubular joints have complexity process of machining,slotted gusset plate connections to tube are used,and this joint can be destroied by shear lag,because ofpartly connection of tube and plate.Analysis on the influence of shear lag to the ultimate tensive capacity of joints was carried on.Through a lot of calculation and analysis,some conclusion is presented and compared with relevant design codes. |
