输电线路钢管-插板节点面外抗弯性能试验研究

Jianzhu Gangjiegou Jinzhan
为研究特高压输电钢管塔C型插板连接的典型节点面外抗弯性能，进行了10个足尺K形节点面外抗弯承载力试验，研究了插板厚度、节点板厚度和螺栓颗数对节点面外抗弯性能的影响。在此基础上，建立了节点有限元有效模型并进行了参数分析，考察了插板与节点板厚度、螺栓颗数与螺栓直径、主管径厚比、斜管径厚比以及钢材强度对节点面外抗弯刚度的影响，提出了此类节点面外抗弯刚度的建议计算公式。研究结果表明：（1）在所有试验工况中，插板和节点板厚度引起的节点初始转动刚度值最大增幅为40.28%，螺栓颗数引起的节点初始转动刚度值最大增幅为

整段拼装式输电塔对接节点承载力试验研究

Jianzhu Gangjiegou Jinzhan
针对角钢铁塔设计出一种上下两端完全分开，形成独立的结构，各段间采用圆形座板式对接，该种结构型式减少了主材接头处螺栓群，有利于改进现有施工组塔方式，提高组塔效率和施工安全性，同时该种结构型式减少了主材接头处螺栓群，为机器人登塔作业提供便利条件。其中，对接节点是保证整塔稳定的关键结构，为获取对接节点承载机制、破坏模式及极限承载力，进行了10个足尺节点抗拉承载力试验，考察了底板厚度、底板直径、孔位直径和螺栓孔径对节点荷载位移曲线及承载力的影响。同时建立了对接节点的有限元有效模型，进一步拓展研究节点的底板尺寸 ...
