For the purpose of elucidating the influence that the difference in aeration method gave in smoke shield performance, an aeration experiment at the normal temperature was carried out using a full‑scale model like the fire experiment. By the experiment, static pressure differences between aeration room and outside and The wind velocity of the ingredient vertical for the upper surface and the perpendicular surface in the smoke shield opening were measured. As a result, the following things were shown. 1) Non-dimensional static pressure difference 3* is almost proportion to smoke shield performance. 2) Upper aspect non-dimensional wind velocity ratio 9X* is almost proportion to smoke shield performance. 3) The achievement of smoke shield requires the thrust from the perpendicular surface and the upper surface which are orthogonally crossing.
