“…Such decrease is visually exemplified by the plots, indicative of the simulation's attainment of the set convergence standard. When RMS residual values were observed below the prescribed 0.0001 threshold, the simulation's successful achievement of the desired degree of accuracy and reliability was affirmed [15,16]. This convergence establishes the results as trustworthy and accurate representations of the building's response under simulated wind conditions.…”

Understanding the response of buildings to wind loads is critical, as these forces can generate significant pressure and suction, potentially leading to structural failure if overlooked. This research was focused on examining the effects of openings on triangular-shaped buildings when subjected to high wind load conditions. Utilizing CAD modeling and Computational Fluid Dynamics (CFD) simulations, the analysis was executed through the ANSYS simulation package. Subsequent Fluid-Structure Interaction (FSI) studies were conducted to ascertain shear stress and lateral deformation. The studies encompassed building models both with and without openings, with the evaluation of induced pressure and velocity. The resultant drag on buildings incorporating openings was discovered to be 6679N lower than those without openings. Furthermore, an analysis employing M25 concrete indicated a 33.133% reduction in lateral deformation in buildings with openings as compared to those without. For buildings constructed with M30 concrete, a 32.173% decrease in lateral deformation was observed. Despite the informative findings, it should be recognized that the investigation was confined to a particular range of wind load conditions and did not consider extreme scenarios. Dynamic wind effects and long-term structural behavior were not included in the current analysis. Therefore, while this study elucidates the importance of wind load analysis and structural reinforcement for maintaining building stability, further research is warranted. Such future investigations should consider broader simulation models, encompassing diverse building shapes and wind load conditions, and account for additional influential factors.

Consideration of vortex shedding response is important for high-rise chimneys when air flow causes strong vibrations of the structure in a certain range of wind speeds when the frequency of natural vibrations of the structure coincides with the frequency of Karman vortex shedding. Among the methods of protection against vortex shedding response, for example, the use of dampers, but the most interesting results show the optimization of enclosing constructions of high-rise chimneys, capable of reducing the amplitudes of lateral forces of wind effects caused by vortex shedding. Therefore, in this research, a study of the applicability of lattice enclosing constructions to protect high-rise chimneys from vortex shedding response by reducing the amplitude of wind effects is considered.
