    Monopole structures are used as telecommunication towers, especially in urban areas where zoning is difficult. The load hypothesis that predominates their design is wind, since most of the collapses are due to this effect. The most critical part that is more prone to failure in the towers is the bolted flange joint, which requires a special focus in the design to guarantee its resistance and performance over time. In the present investigation, a finite element model was obtained that approximated the actual structural behavior of bolted flange joints. The finite element models were developed in a specialized software and monotonic lateral load tests were performed for their validation. The results obtained by measuring loads and displacements in the tests were compared with those obtained in the finite element model, showing non-significant variations in the points of interest of the bolted flange. The finite element model was useful for predicting the structural behavior of the flanges, making the design process more dynamic.
