Peak Velocity Pressure of Air Traffic Control Towers: A Comparative Study

Abstract

The aim of the study was to compare the structural resistance of air traffic control towers (ATCTs) in Europe over 100 feet (30.48 meters) in height by determining their peak velocity pressure. A comprehensive examination was conducted on the ATCTs of 64 airports across Europe, with a reference to the EN-1991-1-4 criteria. The findings revealed notable differences in wind speeds and peak velocity pressure values experienced by ATCTs located in diverse geographical regions of Europe. The Athens Airport ATCT recorded the highest peak velocity pressure at 2.52 kN/m², while the lowest value was recorded at Zagreb Airport ATCT at 0.89 kN/m². These differences play a crucial role in determining the structural resistance of ATCTs. ATCTs exposed to high peak velocity pressures should use stronger materials and incorporate aerodynamic designs. Considering the significant influence of geographical location on wind loads, these results provide important insights into the safety of existing and future ATCTs. It is recommended that these findings be extended by investigating ATCTs in different geographical regions and that structural design strategies against wind loads be more thoroughly investigated in future studies.
