| Super-tall slender structures are increasingly prevalent in modern architecture, but their stability and performance are heavily influenced by fluid-structure interactions (FSI) induced by wind loads. Accurate simulation of these interactions is crucial for ensuring structural integrity and safety. This study aims to conduct numerical simulations of FSI on super-tall slender structures using advanced two-way coupling techniques. The primary objective is to develop a comprehensive understanding of the complex interactions between fluid flow and structural response to inform design and optimization strategies. The novelty of this study lies in the utilization of two-way coupling techniques, which allow for simultaneous and iterative solving of fluid dynamics and structural mechanics equations. By incorporating bidirectional feedback between the fluid and structure, this approach captures intricate FSI phenomena with high fidelity, enhancing the accuracy of predictions. The proposed framework involves integrating computational fluid dynamics (CFD) and structural analysis methods within a cohesive simulation environment. The CFD solver models turbulent airflow around the super-tall structure, while the structural solver accounts for the deformation and response of the structure under fluid loading. The coupling between the two solvers enables mutual influence and interaction. Numerical simulations are performed for a representative super-tall slender structure subjected to varying wind conditions. The simulations capture detailed fluid flow patterns, structural deformations, and dynamic responses. Analysis of the results reveals the intricate coupling between fluid dynamics and structural behavior, highlighting the importance of considering FSI effects in structural design. The study demonstrates the effectiveness of two-way coupling techniques in accurately simulating FSI on super-tall slender structures. The insights gained from the simulations contribute to a deeper understanding of the dynamic behavior of these structures under wind loading. Ultimately, this research facilitates the development of more resilient and efficient design practices for super-tall buildings in complex wind environments.
