摘要
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.
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.
