The passage of wind may cause any tall structure to shake in both the "along wind" and "across wind" directions. Buildings intended to meet lateral drift criteria may nonetheless swing excessively during a storm, even if they have been designed to meet these requirements. As structures rise in height, they become more susceptible to wind oscillations and pose a hazard to the tall building. Oscillations may cause pain to the inhabitants even if the structure is not in danger of collapsing. As a result, a precise evaluation of structure movement is a precondition to serviceability. There are a few methods for determining the Wind Load Response of tall structures.
Air currents moving in a certain direction are a sort of wind that is apparent to the human eye. Civil engineering constructions have a severe drawback in that they may load any anything that enters their way. In rocky terrain, the wind travels at a slower pace, whereas in flat ground, it travels at a faster pace. Using wind data from three distinct terrain types and three different building heights (Lower Moderate & High Rise), this research examines the effects of story drift, shear,& support responses on three various building heights. ETABSv9.7.4 is used to assess all 12 models of G+5, G+10, and G+15. The current study is an excellent source of information regarding the variability into drifting, shear with model height and the % variation into drifting, shear of the same model in various terrain categories.
