- Abstract
- [ABSTRACT IN ENGLISH] This evacuation model was developed in the course of a Comprehensive Technologies Development Project of Ministry of Construction: Development of Fire Safety Design Method of Buildings. This model is intended to be used in evacuation safety designs of buildings to evaluate the effectiveness and to help find drawbacks of the interior spaces of buildings from the viewpoint of evacuation in emergency. This model, assuming an orderly movement of people of uniform walk speed in the direction designated by designers, predicts the numbers of occupants in each space and of crowdings at each opening on the designed evacuation routes at arbitrary time after the start of an evacuation. Based on such predictions, a designer will be able to estimate the time required for evacuating the building and recognize the undersirable feature in his design of the evacuation routes. Then, he will be able to feed these informations back to the determination of the capacities of the routes or the protection measures of the routes during an appropriate time by means of smoke control, etc. This report gives the theory of the model, the documentations and the guide for users of the computer code established based on the theory and the list of the code. Some date for the purpose of validating the model are given too. On developing this model, reasonable attention has been paid of the existing results of researches on the evacuation problems, but needless to say, there will still be plenty room for improvement. In addition, since it was necessary to imagine ordinary spaces as the object spaces on which this model apply, so there may be cases where the present code does not work very well. In such cases, the author would be happy if the potential users modify the code in more convenient form. It is in this intention that the detailed descriptions on the code are given in this report.
