This paper describes the study of the smoke-spreading process in a fire of a high-rise apartment building, SKYCITY-MINAMISUNA, and structure of the fire protection measures of the building. In that fire, smoke spread into the escape lobby and the staircase. I understood that the fire door of the lobby had automatically worked but it had not perfectly closed because of wind pressure. I analyzed this fact as a failure process in structure of fire protection measures and proposed the subjects of design conditions for fire protection planning based on the idea of fire phase model and fail-safe structure.
