Mathematical approach to performance specifications of fire safety in an urban area

本研究旨在从性能规范的角度找出影响城市消防安全水平评价的主导因素，并提出基于数学方法的城市消防安全水平评价建议。本研究的主要结果如下：(1)分析了火灾安全水平的变迁及其主导因素；(2)建立了地震后火灾爆发的评价模型，并对火灾爆发的对策进行了评价；(3)提出了新的地震后广域疏散方案的方法；(4)从确保地震后广域疏散的安全水平出发，要求城市火灾的安全水平。

This study aims to identify the dominant factors for evaluating the level of fire safety in urban area from performance specifications point of view, and to make a proposal for evaluating the safety level based on mathematical approach. Principal results of this study are as follows ; (1) to analyze the transition of the level of fire safety and its dominant factors, (2) to develop the evaluation model of fire breakout after a big earthquake and to evaluate the countermeasure against fire breakouts, (3) to propose the method of the new wide area evacuation plan from post-earthquake fire, (4) required safety level of urban fire from securing safety level of wide area evacuation from post-earthquake fire.
