With the urbanization process in recent years, many buildings are being constructed between two different mountains. In this case, however, topographic wind speed-up effects must be considered for securing the safety of structure. Thus, this study compared topographic factor and turbulence intensity with standard value by implementing wind tunnel test through different distance lengths in accordance with the height of mountain using 4 representative types of simplified 3-Dimensional Hills that funneling effect may be shown. Through the experiment, this study aims to suggest quantitative fluctuation of wind speed according to the change of distance lengths and provide hills that is affected by the valley wind effect as preliminary data for assessment of wind speed-up effects.
