CALCULATION OF STEEL ANTENNA MAST ACCORDING TO EUROCODE

Summary: The paper presents the calculation of steel antenna mast according to Eurocode with the aim of testing the mast utilization for the needs upgrading new network for mobile telephony. A mast is made of four segments with connections and the lower two segments are with variable cross-section. At the highest segment are placed two platforms with carriers for antennas and mobile technology. It presents the analysis of the loads according to the German standards DIN to compare with the Eurocode. Keywords: antenna mast, antenna carriers, mobile telephony, Eurocode
