| Outline of Final Research Achievements |
The fire behavior in a room and a compartment is controlled by the material and dimensions of fire load and the relative position among combustible materials. Therefore, when performing performance-based fire safety design of a building, a design fire source is assumed according to how to use space, such as the material, amount, surface area, and arrangement of combustible materials in a room and a compartment.
In order to estimate the design fire source, the field survey of fire load is being conducted for the purpose of collecting information regarding combustible materials in a room and a compartment. However, there is a serious problem that it takes a huge amount of time because the number of measurement item on the past method about field survey of fire load are large. Therefore, in this study, we conducted a field survey of fire load using a 3D scanner. Then we proposed the development of a survey method and examined its reliability.

| Academic Significance and Societal Importance of the Research Achievements |
建築物の火災安全性能を適切に評価するには、建築物内で発生する火災の予測技術を向上することが必要である。予測技術が向上すれば、建築物の安全性を確保しながら、適切に設計デザインの自由度を拡大させ、建設コストの経済性に対する選択肢も拡張されることが考えられる。火災の予測技術を向上させる上で、火災の激しさなどを表す設計火源の想定が不可欠である。設計火源は建築物空間内の可燃物に影響を受けることが明らかになっており、効率的な可燃物の調査方法を確立すれば、建築物の火災安全性を確保するための予測技術の高度化に寄与することになる。
