Özet
Understanding the wind effects on the building is of great importance in the architectural field. The present study focuses on the analyse of various simple plan shaped buildings with different aspect ratios under various wind velocity to examine wind pressure distributions, and velocity distributions on and around the building. Therefore, the main evaluation criteria are plan shapes, building aspect ratios, storey height and wind velocity. With this aim, ANSYS Fluent 20.0 Computational Fluid Dynamics (CFD) software package program is used for the analysis. As a result of the study, it has been observed that the aspect ratios of width/height ratios (WR) and length/height (LR) ratios, building plan shape and wind velocity significantly affect the wind characteristics of the building. It has been observed that the change in the plan geometry did not have a significant effect on pressure coefficients on leeward surface. However, the change on the plan shape or variation in the aspect ratios have critical effects in the pressure coefficients on side surfaces. As the length of the building increased, the pressure values increased on the side surfaces. On the other hand, it has been noticed that building aspect ratios have significant impacts on pressure values. The most critical pressure values were observed on windward surface and on side surfaces in D4 model which has the greatest length ratio (L/H) of 6.0.
