Abstract:Zhoukou Radio and Television Transmission Tower is a multifunction steel structure tower, with the main function of radio and television broadcasting, as well as functions of sightseeing, food and beverage, and exhibition, etc. The    total height of whole steel structure is 286 meters. The structural system of the tower consists of mega spatial truss column and mega spatial truss beam. The calculation of wind load on the structure was introduced as well as earthquake spectrum analysis under fortification earthquake. The analysis results show that the structure can meet the requirement of performance indices under fortification earthquake and wind load is the controlling load. The impact of temperature effect on the high-rise structure was calculated. The temperature effect treatment measures of the inter-story column system were proposed including the exposure of the wellhole column and set of the vertical expansion joints inside the structure. Finally, the key design points and treatment measures of tower building′s rotating platform were introduced. The design method and treatment measures in this project can be used as reference for the structural design of the same type of high-rise structures.

Keywords:high-rise structure； TV tower； structural system selection； seismic response； temperature effect
