REDUCING THE DESTRUCTIVE EFFECTS OF WIND FORCEIN HIGH-RISE BUILDINGS BY INVERSE AIRFOIL

Wind load on high rise building had alwayse been one of the most concerning issues forresearchers and designers. In this article, it has been tried to find a way to attenuate destructive effectsof wind load on tall buildings. In other words, a concrete special moment frame was modeled so thatan airfoil inversely placed on some heights of the structure. The goal was to assess performance of thisnew tools on improvement of the structure behaviour against wind force. According to results, theinverse airfoil on the structure could improve the structure efficiency because of a negative lift forceimposed on the building. Therefore, utilizing an inverse airfoil on different point of a tall building is aproper solution to protect it against wind force.
