| Research Abstract |
In this study, we discuss the evacuation measures in high-rise office building after the large-scale earthquake. According to the cases of past earthquakes, as the evacuation measures of whole building, it is important to give priority to upper floor evacuees, and to control excessive congestion in the staircase. For high-rise office building, there is concern of smoke propagation by fire through damage of compartment in staircases and vestibules due to the earthquake. And also, it concerns that the capacity of the stairs to the total evacuees relatively becomes small for the huge buildings. We use the evacuation simulation model, and compare the result between concurrent evacuation and upper floor-first evacuation. And we discuss about the effectiveness and agendas of evacuation measures after an earthquake.
