[提要]  采用空间桁架体系为计算模型，分析了洛阳电视塔在静力作用下的线性、非线性反应。另外，在分析了结构单向和三向振动特性后，采用自编程序对其进行了单向地震和三向地震作用下的计算。

A steel space-truss structure of Luoyang TV Tower is discussed. The difference of the response of the
structure between taking account of the influence of geometrical nonlinear and linear is studied when it is acted by the wind loading, and then the dynamic character of the structure is analysed. At last, by using steyby-step integration procedure, we calculate the seismic reponse of the structure subjected to the three-dimension and single-dimension seismic actions considering geometrical nonlinear and linear.
Keywords: TV Tower; steel structure; nonlinear analysis; three-dimension seismic actions
