通信单管塔抗震性能分析

为确定通信单管塔在地震载荷作用下结构设计的安全性，选取典型的通信单管塔为研究对象，通过合理的结构简化建立有限元模型；参考规范中8烈度罕遇地震的要求，通过静力分析法、振型分解反应谱法和非线性时程法分析计算结构的抗震性能；对3种计算方法得到的结果进行对比，得出不同分析方法计算结果的差别；通过综合分析计算结果评估通信单管塔的抗震性能.

Analysis on anti-seismic performance of communication monopole

To confirm that the design of communication monopole structure is safe under seismic load, a typical communication monopole is taken as the research object and a finite element model is built by reasonable structure simplification; according to the requirements for the rare 8th seismic intensity in the specifications, the anti seismic performance of the structure is separately calculated by the methods of static analysis, response spectrum analysis and nonlinear time history analysis; the difference of the results are obtained by comparison of the results of the three analysis methods; the calculation results are comprehensively analyzed to evaluate the anti seismic performance of the communication monopole.
