Communication monopole with its concise and abound change the appearance, convenient connection modeless basal area, etc, become the main design form of transmission towers and communication tower in foreign, in recent years in China, has started extensive use of good prospects for development.Communication monopole is a relatively small cross-section, large diameter-thick slender structure, belong to the thin-walled, high-rise steel structure, so wind load influence is bigger, in the wind load, communication monopole the ultimate bearing capacity analyzing is directly affect the structure security and practicability. At the same time, the earthquake is unavoidable to nature disasters, structural damage is impossible to ignore, in order to avoid earthquake disasters, stem damage caused by the times of severe disaster accident, polygon communication monopole seismic response analysis is still need.This paper begins by describing monopole current situation.Contrast different communication monopole structural forms mechanical properties and applicability, introduced polygon communication monopole superiority.Then introduce the nonlinear theory and nonlinear finite element analysis theory, establish polygon communication monopole models. And then expounds the wind load theory, based on the random vibration theory, simulation got the multidimensional related fluctuating wind load time-history sample curve by M.Shinozuka methon, and inspection. In the mastery and regulate structure and familiar with the relevant provisions of the basis of using finite element analysis software ANSYS, the structural analysis of wind load limit bearing capacity. Finally, this paper using ANSYS software add earthquake spectrum and earthquake wave, got three different forms of the polygon monotube communication tower structure for seismic spectrum analysis and transient analysis.
