Abstract

The effect of wind as a dynamic load on structures can vary greatly depending on geographic location, topography, building height, and the characteristics of the building itself. Therefore, careful calculations and an in-depth understanding of these factors are essential in the design of safe wind-resistant structures. For tall buildings, the structural response due to horizontal loads due to wind loads is much greater than vertical loads. This paper reviews the analysis of wind loads as static lateral loads against the internal forces and inter-story drift that occur. A review was carried out of a reinforced concrete structure building with a plan size of 25 x 10 m; the frame height is 32 m, with a total of 8 floors. The speed of the wind is 120 mph. The structural response reviewed compares internal forces, deformation, and inter-story drift under wind loads with variations of wind speed factors based on surface roughness and topographic influence factors (slopes and hills). From the analysis of the effect of wind loads on building structures, it can be seen that wind speeds in flat areas without obstructions (exposure D) and slope areas have more significant wind speeds compared to the city center and hilly regions.
