In this study, human movement characteristics in the stairwell of super high-rise buildings have been investigated. Based on fire drills, a total 229 participants and 7 cases of evacuation were performed in Taipei 101 and New Taipei City Hall which are about 508 m and 140 m tall, respectively. Within these cases, cases 1 to 6 were carried out in Taipei 101 and case 7 was carried out in New Taipei City Hall. The processes of evacuations were recorded by the cameras and observers in the stairwells and the data were extracted out manually. The speed characteristics of occupants when evacuating down in the stairwells for various floor intervals have been presented and analyzed. The mean speeds of cases 1 to 6 measured for vertical speeds concentrate within in a range from 0.22~0.24 m/s and the walking speeds are within 0.61~0.65 m/s. In cases 1 to 6, the temporal maximum density of oc¬ cupant on the stair landing was 1.8 person/m2. For case 7, the mean vertical speed and walking speed are 0.31 m/s and 0.98 m/s respectively, with the temporal maximum density of occupant on the stair landing, 1.3 person/m2. In addition, some evacuation behaviors were observed and discussed such as overtaking, group movement, and use of the cell phone, etc. In this study, the re¬ sults are important for improving fundamental parameters to evacuation models in super high-rise buildings and compared with the results found from other studies for evacuees without impairment.
