Abstract

The two major loads considered in high-rise buildings are seismic and wind loads. In such buildings, safety means the stability of a structure against the effect of both loads as well as gravity loads. This paper studies the effect of different levels of lateral wind loads on three different seismically designed high-rise buildings on ETABS software. A 40-story high-rise building was seismically designed according to three different resisting systems (special moment resisting frame, shear wall system and dual system). These systems were designed according to a moderate seismic of acceleration 0.25 g and a soil type of Sc which symbolizes the description of a very dense soil and soft rock. Each of these systems were subjected to three global wind speed levels under wind exposure D, low wind level of 45 mph, a moderate level of 85 mph and a high level of 125 mph. The results showed that each system reacts differently not only under the effect of seismic but also under the effect of wind. They also showed that shear wall system failed under the effect of high wind, on the other side it is the most effective system under the effect of seismic and the cheapest one. The dual system is the most desirable system to be used against wind load and the most economical one. Special moment resisting frame system it is desirable to resist high wind load and seismic load but in both cases it costs slightly more than the dual system.
