摘要

Purpose

A feasible solution to the challenges relevant to urban civilization has been the construction of high-rise buildings. However, the impact of lateral forces like earthquakes and wind is considered important in the design and safety of high-rise structures. These types of structures are especially susceptible to wind. The present study is carried out to examine the vibration performance of different types of lateral load resistance systems against wind loads i.e., moment-resistant frame system, shear walls at the corner and centre of the building, bracing (V type and X type), and tube systems.

Method

In the context of this research, a detailed wind analysis is carried out on a diverse set of building models, which encompasses varying numbers of stories, including low-rise (10 storeys), medium-rise (20 & 30 storeys) and high-rise (40 storeys) buildings. The performance of the building models is measured and compared by considering various structural response parameters like storey displacements, base shear, storey drift, and overturning moment.

Result

The results showed that shear walls, bracing, and tube systems effectively reduce lateral displacement, Storey drift, and overturning moment in tall structures. The building with core shear walls exhibit superior stiffness and performance, while X-bracing excels in shorter structures. Moreover, the core shear wall performs outbound among all divisions of structural systems by providing adequate performance and stability in structures by reducing the drift and displacement response.

Conclusion

The study's outcomes provide valuable insights for selecting optimal structural systems to enhance the safety and performance of tall buildings specifically concerning wind loads in densely populated urban environments.
