 Summary:
 The wind as a loading is one of the most significant loads for lightweight structures and their cladding, particularly roof claddings. Underestimation of wind load for design of roof cladding can cause significant damages. Even when strict application of standards is applied for the design, delamination and damage of roof cladding can occur during gusts of wind, as was the case at the Air Control Center building within the "Nikola Tesla" airport in Belgrade during the stormy wind which took place on Jun 16th 2010. Subsequent control calculations, conducted on the basis of anemograph records of wind speed at the site, proved that the roof claddng and its connection to the roof structure could not withstand actual wind loads that occured. The question is whether for the important buildings, particularly those with constantly measured wind speed and available data, the design should be based on the data for averaged wind speeds given in codes or on the available data based on actual measurements and real time extreme values of wind speed, which is more accurate for numerical simulation of the wind gust loads.
