摘要:
共享铁塔是指在输电铁塔上加装通信平台,实现电力和通信的资源共享.为满足挂载高度和输电塔杆系分布的需求,可通过具有不同钢管间距的挂载连接件实现通讯设备与输电塔的相互连接.为研究不同钢管间距下挂载连接件的初始刚度、承载性能及破坏机制,设计制作了三个挂载连接件试件,并利用数值模拟建立模型进行了拓展分析.分析结果表明:各部件可整体协同变形,试件最终的破坏模式均为钢管于底部加劲肋或顶部端板处断裂,挂载连接件的变形形态受钢管间距影响较为明显,其塑性承载能力和初始刚度随间距的增大而减小,极限位移则随钢管间距的增大而增大.所提出的挂载连接件屈服荷载及位移的计算公式,可为同类的工程设计提供参考.
Abstract:
The shared tower refers to the installation of communication platform on the transmission tower to realize the sharing of power and communication resources. To meet the requirements of mounting height and distribution of the transmission tower, the interconnection between the communication equipment and the transmission tower can be realized through the mounting connectors with different steel pipe spacing. To study the initial stiffness, load-bearing performance and failure mechanism of the mounting connector under different steel pipe spacing, three specimens of mounting connectors were designed and fabricated, the model was established by numerical simulation for extended analysis. The results show that the components can be deformed collaboratively, and the failure modes are all fracture at the rib stiffener or top end plate of rectangular steel pipe. The deformation shape of the mounting connector is obviously affected by steel pipe spacing, and its plastic bearing capacity and initial stiffness decrease with the increase of steel pipe spacing, while the ultimate displacement increase with the increase of steel pipe spacing. The proposed calculation formulas for the yield load and displacement of the mounting connector can provide a reference for similar engineering design.
