“…However, the results obtained from wind tunnel testing are influenced by various factors such as the size and shape of the model, the type of wind tunnel used, and the instrumentation used for measuring the wind loads. In recent years, Finite Element-based computational fluid dynamics (CFD) analysis has emerged as a powerful tool for predicting fluid flow using a mathematical model [8].…”

This research paper evaluates the effects of wind tunnel testing on low-rise buildings using a Finite Element-based computational fluid dynamics (CFD) model in order to compare the results of the traditional Directional Procedure (Building of All Heights Method) to the results of the CFD analysis. This study utilized all necessary parameters for the Wind Tunnel Procedure in accordance with the National Structural Code of the Philippines section 207F together with the guidelines prescribed in ASCE 7-16. The mathematical prototype of 3 different buildings with the same dimensions were created using midas NFX, and the necessary boundary conditions for CFD analysis were set up. The pressure caused by wind load on these buildings were evaluated and compared with the Directional procedure in Section 207B of the NSCP (Buildings of all heights method). Atmospheric turbulence was also modelled using Kinetic Energy and Length Scale method utilizing 2-equation k-ε turbulence model. The results show significant differences in pressure effects on walls with considerable number of openings and unique façade features. CFD results also show accurate internal pressure and velocity profile in areas near the wall openings and building edges. This research is particularly relevant for the design and construction of buildings in areas prone to strong winds, such as the Philippines, where accurate wind load calculations are crucial to ensuring structural safety and integrity. While numerous studies in other countries have explored the impact of wind on low-rise structures through mathematical simulations, there remains a substantial gap in the Philippines regarding research concerning wind tunnel effects on structures using mathematical and numerical approaches. This study aims to fill this gap by connecting the existing National Structural Code of the Philippines with contemporary trends in mathematical simulations.
