چکیده مقاله :
In the telecommunication industry, guyed towers are one of the important structural subsystems. They support a variety of antenna systems at great heights to transmit radio, television and telephone signals over long distance, thus preserving them in events of natural disasters such as earthquake is of high priority. Also, domes and transmission stations functions depend on transmitted information by guyed towers. In this paper, seismic behavior of guyed towers are studied. For that, one guyed tower in 9 clusters of guys is studied under earthquake force. This research was accomplished on the base of wind and earthquake forces and tower interaction to these forces. Here, the effect of earthquake force and tower response to seismic events are studied. At first, time history analysis is used in determination of towers vibration natural modes, then, under time- acceleration components of El-Centro earthquake, spectral analysis are accomplished. Analysis outputs are two parameters including frequency and maximum lateral displacement which are provided using ANSYS software. The results are used in comparing two different calculation models: genetic programming and cellular automata.
