This study evaluates the structural behavior of a 20-story concrete office building with a rigid frame system under varying wind loads. The analysis is conducted using ETABS software at wind speeds of 40, 60, 80, and 100 mph. The internal forces, including deflection, shear, and overturning moments, are assessed under these conditions. The results demonstrate compliance with ACI318-19 code requirements and address critical factors like deflection limits and stability. The study further highlights environmental impacts, neighboring building effects, and wind movement in the width direction, ensuring safe and efficient high-rise building designs. It has been concluded that deflection, shear forces and overturing moments increase at a similar rate with the increase in wind speed. Additionally, the drift caused by wind does not pose a significant risk compared to that caused by earthquakes, for this reason, the American code does not specify a limit for wind induced drift as the H/500 limit is an approximate value derived form previous experiences. This Study recommends that future studies on this system continue, taking into account seismic loads. And should include a comparison between this system and other systems resistant to wind and seismic loads focusing just on cost and method of construction in our country Sudan.
