| 摘 要： | 文章通过模拟风荷载的拉、压往复作用,对输电塔的钢管K节点进行疲劳试验研究.当节点在50万次循环后仍未破坏,则停止疲劳试验,并对其进行静力加载破坏试验,得到了节点失稳破坏的临界压力和相应的破坏形态.采用2种有限元模型对节点进行了失稳分析的数值模拟,结果表明,2种模型计算的临界力十分接近.

| Abstract: | By the simulation of the pull and push reciprocating actions of wind load,the experimental research on the fatigue performance of steel tube K-joint of transmission tower is carried out.The fatigue experiment is stopped when the K-joint has not failed after 500 000 times circulation,then the static test is conducted and the critical force and corresponding failure mode of the K-joint are obtained.The numerical simulation for the failure analysis of the joint is carried out by using two types of finite eleme... |
