  • Abstract

    The fast process of urbanization and the growth of the need of high-rise buildings have caused the essential progress in the development of tall buildings construction and design. Wind load is one of the several environmental loads that are exerted on tall buildings that dominate in terms of control over structural safety, serviceability, and comfort of occupants. Unless properly considered in the design phase, the forces caused by the wind may result in excessive lateral displacement, inter-story drift, dynamic acceleration and local structural damage. The proposed study will provide the detailed study of the effect of the wind load on the tall buildings in the form of analytical, numerical, and codal method. The study combines wind engineering, computational modelling as well as parametric analysis to test the behaviour of tall buildings under different wind conditions. A standard reinforce concrete structure, which comprises of steel is modeled using the finite element techniques and the wind loads are applied as per the international codes. The paper examines how the building height, aspect ratio, structural system, terrain type and damping ratio affect structural response. Base shear, overturning moment, a sideways movement, and acceleration are the important performance indices. There is also a comparative evaluation of the dynamic and the static wind analysis techniques. The findings indicate that dynamic effects manipulate greatly the reaction of slender buildings and are to be introduced in contemporary systems. In addition, structural control strategies and aerodynamic methods are mentioned as the effective mitigation measures. This study can be useful to the structural engineer and other researchers about maximizing the design of tall buildings to overcome wind-related broadsides to promote safety, sustainability, and resilience.
