| 摘 要： | 结合工程实际,对河南广播电视发射塔中"桉叶糖"异型钢管"X"节点缩尺试验进行了研究,讨论了实验的加载装置、测试结果和有限元数值计算结果,分析了这种节点在设计荷载下的受力性能和影响该节点荷载-应力曲线的主要因素.结果表明,这种"桉叶糖"异型钢管相贯节点在设计荷载作用下具备足够的刚度和强度,满足设计需求;有限元计算结果与试验实测结果吻合较好,有限元分析模型可进一步推广至未实测的"X"节点.

| Abstract: | Two crossing X connections of Anyetang special steel pipe used for Henan Broadcast and TV Tower are investigated on the basis of practical projects.The paper presents the design of reduced scale test setup,experimental and finite element calculating results,and also the major factors influencing the load capacity of these special joints.The experimental results show that the special crossing joints have sufficient strength and rigidity,and can meet the design requirement. The experimental results agree well with finite element(FE) analysis,so this FE analytic model can be applied to other untested joints located in Henan TV tower. |
