In order to confirm the wind pressure distributions of dome structure, the wind tunnel experiments, which were tried to reduce the inconsistency of Reynolds number between model scale and actual scale by attaching the roughness on the model surface, were conducted. Indoor airflows in dome structure were calculated with Computational Fluid Dynamics (CFD) applying experimental results to inflow conditions of vent holes. The followings are clarified from the results. The wind pressure distributions are different according to presence of surface roughness. Reynolds number significantly influences the experimental results of the surface-pressures. The velocity of airflow at center of the dome is comparatively low, but arrangements of vents are sufficient for ventilation of whole inside air.
