Abstract
Recently, evacuation safety of building resident become the major concern, as the building has been higher and more complicated. Required evacuation time using stairway is longer in high-rise buildings, moreover it is impossible for the disabled to evacuate by using stairway. For this reason the study on the effectiveness of using elevator for evacuation is progressing. This study shows the flow coefficient of hoistway when elevator is moving. The results of this study can be used for the study of elevator piston effect as basic data. Experiments were performed in 5 different hoistways at 3-story and 2-story buildings. According to the result of flow coefficient experiments, average flow coefficient is 0.954. Considering the $4{\sigma}$ to guarantee 99.99 % reliance, it is 0.86. This result is 3.6 % bigger than 0.83 that Klote and Tamura suggested. It represents that the maximum critical pressure is decreased about 7 % on the same condition of elevator and elevator shaft. When the smoke control performance of high-rise building is evaluated, the result is significant economically by applying a more realistic and less value of elevator piston effect.
