Numerical Investigation on Impact of Wind Loading on High Rise Structure Using Ansys

Abstract

In modern architecture, irregular geometries have become increasingly popular. However, when designing tall buildings, it is crucial to consider the impact of wind loads, which can cause dangerous torsion if the plan geometry is irregular. To properly assess wind loads, it is necessary to analyse them during the design process. One way to mitigate wind loads is through aerodynamic modifications. This research aims to evaluate the effectiveness of different aerodynamic modifications on various shaped models using computational fluid dynamics simulation software called ANSYS. The modifications include chamfered and recessed corners, as well as Y-shaped and tapering forms. The study examines coefficients of drag and lift, as well as the dynamic behaviour of the models. Material changes are also evaluated. The findings highlight the importance of considering wind loading in the design and analysis of high-rise structures. Ultimately, this research can help improve the safety and design of high-rise buildings located in areas prone to high wind speeds.
