As per the NOAA data, the intensity of cyclones and wind gusts impacting low rise and high rise building structure has increased causing heavy damage and destruction. The damage cost and deaths has increased manifold in last 10 years. The hurricane “Katrina” has become the costliest in the history which was “category 3” type hurricane and causing immense damage to building structures and more than 1900 deaths [23]. The external air flow conditions (wind fluctuations) causes damages to structure by making roof membranes flutter and flap due to uplift pressure [24,25]. The loss of roofing causes various problems like “rainwater intrusion, interior restoration and occupant displacement” [26]. The intermittent suction is generated by the corner vortices which are due to uplift pressure. The debris which is airborne causes damage to other structure when wind is in downward direction [27]. The primary cause of aerodynamic stresses on a low building's roof and walls is the interaction between wind flow and the building's surface. The behavior of this interaction is primarily determined by the geometry and flow characteristics of the building. However, it is common for architects and engineers to overlook these factors during the construction of buildings. Instead, they tend to prioritize the structural and design elements of the structure, such as walls, overhangs, foundations, and roofs. The evaluation of building structure under external load conditions was previously conducted using wind tunnel testing. The experimental testing was based on determination of drag force and pressure coefficients. However, the recent techniques are based on usage of Computational Fluid Dynamics (CFD) for evaluation of structure stability. The CFD analysis requires data on type of external air flow, magnitude of air flow and turbulence conditions. The CFD technique aims to develop more reliable models which can better predict the damage caused due to high wind flow conditions and aid in developing more robust designs.
