Abstract

Regarding the progressive improvement of Space Technology in all developed countries, and consequently developing countries, including Islamic Republic of Iran, the optimization of design and utilization of the communication equipment, especially dish antennas, is of great importance for transmitting and receiving data at relevant ground stations. With the advent of science-related space technology, including communication engineering, and given the great sensitivity of these dish antennas, it is necessary to design the related structures of this field more carefully than ever before. So far no comprehensive study in aforementioned structures has been carried out, considering the great use of steel as a favorable material in designing and constructing the structures necessary for the installation of these antennas, in this paper, first the instruction of seismic design and assigning loads for structures is presented. The required two steel structures are simulated and designed to deploy antenna systems, which are typically used at stations. Finally, due to specific analyzes and controls, the efficiency of the developed criteria has been determined. Among the few results obtained, it can be noted that considering the Soil Structure Interaction would impress the output results with a difference rate more than 500%, respectively at operational condition.
