| Abstract: | In this paper,the equation of vibration for the self-supporting microwave communication tower sub-jected to multiple seismic inputs is established,and some formulas about the statistics of random responseof tower are given.The random response analysis for microwave communication tower in Shanxi provinceis completed by use of the rotational power spectrum of seismic ground motion given and modified Kanai-Tajimi's translational power spectrum. Based on the numerical results,some conclusions with practicalsignificance are drawn.Finally,some problems are discussed. |
