Recently a fire risk has increased in Seoul due to the rapid increase in the number of high-rise buildings (50 floors or above 200m). Establishing fire safety of high-rise buildings is urgent through the establishment of an installation standard of the middle refuge floor (Ch.3), reinforcement of fire· refuge facilities (Ch.4-1), a measure to count stack effect and the ensurance of the high fire resistance of high strength concrete (Ch.4-2·3), the integrated system of the disaster management of buildings (Ch.5), The middle refuge floor of high-rise building is installed within 25 floor(s) in maximum, simultaneously the safety of occupants should be secured by adding refuge stairs in accordance with floor space, enlarging the width of the entrance. Installing the middle refuge floor of high-rise buildings on every 30th floor in maximum, which is the legal standard, can bring serious accidents by causing the refuge limit time exceed the final refuge competition time. Additionally, safety for the structure of high-rise buildings is secured by expanding fire fighting facilities with the performance based design and introducing the performance based design for the building structure. At the same time, reinforcement for the fire water source, automatic fire detection installation, wireless communication auxiliary devices, and smoke control system is established. To reduce the stack effect of high-rise buildings, a method based on the architecture plans and a scheme of facilities need to be considered concurrently. Also, the mitigation strategy of high strength concrete spalling needs to be established, The integrated system of the disaster management of high rise buildings with 3D indoor spacial information data base is required based on 『The special law for the safety management of high-rise buildings and complex buildings connecting to the underground』for the disaster management of high-rise building such as fire suppression and refuge plans.

Recently multiple-user buildings has drawn big attention by citizen and policy-makers due to the ever-increasing fire incidents and the potential danger, Fire prevention and evacuation facilities and should be examined, and the locational characteristics of fire incidents in multiple-user buildings should be identified to prevent fire incidents and minimize victims. The purpose of this study is two-fold. The first is to improve evacuation facility measures in multiple-user buildings, and the second is to identify and zone the concentrated areas for fire safety management in Seoul. For the improvement of evacuation facility measures in multiple-user buildings, this study modeled to simulate evacuation capability by various fire safety facility options in kosiwon(mini-rooms residence) as a sample type of multiple-user buildings and suggested an improvement of evacuation plan to minimize casualties by fire incidents in multiple-user buildings. It is suggested that, if necessary, an evacuation modelling may be applied for the assessment of the suitability of evacuation facilities during the inspection of building fire safety. For the zoning of concentrated areas of multiple-user buildings fire prevention management, this study identified and delineated the concentrated areas one the basis of census tract level in Seoul and suggested an intensive management plan for fire prevention and rapid dispatch. Using GIS analysis, the concentrated areas of multiple-user buildings was selected about 211 sites and 2.165㎢, approximately 0.4% of Seoul areas. The analysis suggested that the more intensive and persistent management should be enforced for the selected concentrated areas of multiple-user buildings. Also, the analysis suggested that fire route designation and more 119 centers be necessary for the fire safety of the concentrated areas.
