Abstract
Recently, evacuation safety of building residents becomes the major concern, as the building has been higher and more complicated. Many high-rise multi use buildings are under construction in Korea. 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 being progressed. Elevator shaft flow coefficient is the major factor for the calculation of elevator piston effect. The results of this study can be used for the study of elevator piston effect as basic data. The flow coefficient simulation was performed using FLUENT, commercial CFD program. As a result of the flow coefficient simulation, the coefficient is 0.88 considering the safety factor. This result is verified that the result of experimental study, 0.86 is conservative.
