• Resumen

  • The purpose of this study is to analyze the RRF antenna tower under wind load action, the wind load is viewed from an angle of 0 to the towing cable to the largest angle on the two types of antenna towers, triangle and Square. Both types will produce different wind loads so that we can find out which load is the biggest from a combination of wind directions. The research method is by empirical analysis, calculating the wind load alone while other loads are not counted. As a result of wind loads, the tension cable and load direction correspond to each section and then the resultant values of force and direction will arise. And finally, the force is changed to lift and the anchor will hold the force. The results use of triangle antenna towers is more beneficial, because the wind load that occurs is smaller, thus the construction costs are also smaller. Due to the wind load that works horizontally and will be provided by the tower that stands vertically, the tower requires several retaining cables in a diagonal position, the force that propagates on the diagonal cable will cause a force in the vertical direction or lift, so the lift must be placed using anchors that are embedded in the soil, the large load from the soil that will hold the anchor is determined based on the value of the analysis, the criteria are too light so the anchor will be lifted and friendly, it will cause waste.
