[提要]  采用空間桁架體系為計(jì)算模型，分析了洛陽電視塔在靜力作用下的線性、非線性反應(yīng)。另外，在分析了結(jié)構(gòu)單向和三向振動(dòng)特性后，采用自編程序?qū)ζ溥M(jìn)行了單向地震和三向地震作用下的計(jì)算。
[關(guān)鍵詞]  電視塔  非線性 三向地震作用

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
