Fire Damage Risk Assessment for Buildings by a City Fire in Consideration of Imperfection of City Information

本研究的目的是为了减少计算时间，并提出有效的数据采集技术，以提高城市火灾模拟的实用性。结果表明：(1)改进了高效的辐射换热计算方法和多核并行处理的城市火灾模拟程序；(2)建立了考虑城市信息不完善的城市火灾模型；(3)验证了开口位置对火灾蔓延的影响；(4)提出了一种基于立体图像的高效城市数据采集技术。

The purpose of this study is to reduce of computation time, and to propose of the efficient data acquisition technique because of improvement in the practicality of a city fire simulation. As a result,(1)the city fire simulation program was Improved of efficient radiant heat transfer calculation methods and the multi-core parallel processing,(2)the city fire model in consideration of imperfection of city information was developed,(3)an influence which the position of openings has on fire spread was verified,(4)an efficient city data acquisition technique by a stereo picture was proposed.
