In Korea, considering that the accuracy of fire scenario evaluation is reduced by performance-based design, it is assumed that the sprinkler does not operate. In other countries, the design continues to be researched considering the operation probability of the sprinkler. In particular, the operation probability that divides the effect after operation is analyzed. Therefore, the operation probability was analyzed by considering the effect of sprinkler operation using domestic fire statistics. As a result, it was found that the probability of successful operation for fire extinguishment was 44%, the success of suppression was 32%, and failure to operate was 24%. As a result of a comparison with data from other countries, the probability of operating, 76%, was lower than that of studies from other countries. When comparing the probability results for successful fire extinguishment, success of suppression, and failure to operate, it was confirmed that the probability of successful suppression was slightly different.

Performance-based design for passive building fire safety provisions is accepted by the authority in Hong Kong since 1998. This is also known as the "fire engineering approach", though the performance-based fire code is not yet available. To cope with the use of new building materials, appropriate flame spread tests on materials and components should be specified. After reviewing four standard tests in the literature, i.e. ASTM E1321-97a, BS476: Part 7: 1997, ASTM E84-99/NFPA 255, and ISO 9705: 1993(E), it appears that ISO 9705: 1993(E) is suitable for assessing the flame spread of materials. .

Analyzing fire severity of designed fire scene is necessary for building fire protection. Ordinary building fire times are calculated from statistic data of their fire heat release rates. Building fire is modeled mathematically to deduce its time-temperature function. Basing on this function curve and Simon Ingberg’s fire severity definition, we establish fire severity classification theory for building fire, including definition and equation of its fire severity, and definition of its fire severity coefficient along with calculation of those coefficients of ordinary combustible solids, and calculation and classification steps for building fire severity.

AbstrakGedung merupakan salah satu tempat dilaksanakannya berbagai aktivitas dari sejumlah manusia pada waktu tertentu. Pada saat kebakaran gedung terjadi, semua orang yang berada didalam gedung harus melakukan proses evakuasi agar terhindar dari bahaya api. Permodelan dengan agen merupakan salah satu cara menggambarkan kondisi kebakaran di kehidupan nyata, untuk mengurangi biaya dan bahaya yang ditimbulkan pada saat terjadi kebakaran digedung.Permodelan ini menggunakan pendekatan Multi agen, yang terdiri dari agen karyawan, agen api dan agen pintu exit yang saling berinteraksi dan berkomunikasi. Setiap karakteristik dan perilaku dari agen disimulasikan dengan menggunakan NetLogo pada saat terjadi kebakaran digedung dengan menggunakan skenario perluasan api, skenario penyelamatan, dan proses evaluasi fasilitas pendukung evakuasi.Pengujian dilakukan terhadap kondisi existing gedung dan perubahan rancangan fasilitas pendukung evakuasi seperti scenario penempatan pintu dan scenario penambahan lebar pintu. Setiap satu pengujian skenario dilakukan sebanyak 5 kali percobaan dengan parameter yang sama dan hasilnya akan dicari nilai rata-rata jumlah manusia yang selamat dan jumlah korban yang terkena api sebagai hasil evaluasi fasilitas pendukung evakuasi, selain itu juga dilakukan pengujian terhadap skenario perluasan api dan skenario penyelamatan untuk melihat karakteristik dan perilaku yang dimiliki agen api dan agen karyawan dalam memberikan aksi terhadap proses evakuasi. Kata kunci : Evakuasi, kebakaran, agen, NetLogo, skenario, evaluasi. AbstractThe building is one of place that people do  various activities at a certain time. At the time of building fire occurs, all of the people must make the evacuation process in order to avoid the danger of fire. Modeling with Agent is one way to describe the condition of fire in real life, to reduce costs and the danger posed in the event of a fire halls. This model uses Multi-agent approach, which consists of the employeeagent, fire agent and exit dooragent which interact and communicate. Each of the characteristics and behavior of the agent is simulated using the NetLogo in the event of fire halls using the expansion fire scenario, rescue scenario, and evacuation support facilities to evaluation process. Tests carried out on the existing condition of the building and changes the support facilities such as the placement of doors and the addition of the door width scenario. Each of the test scenario performed 5 times with the same parameters and the results will be sought value average number of human survivors and the number of victims affected by the fires as a result of the evaluation of evacuation support facility, while also testing the expansion fire and rescue scenario for look at the characteristics and behavior of fire agent and employee agent in evacuation process.  Keywords: Evacuation, Fire, Agent, NetLogo, scenario, evaluation.
