    In the context of building evacuation safety verification, evaluations often focus solely on meeting minimum safety standards (e.g., building code compliance). Even when a design fails to meet these standards, feedback on potential modifications for improvement is typically lacking. This study proposes a method for visualizing the analysis results of building evacuation safety plans using heatmaps. This approach aims to clearly identify evacuation safety issues within floor plans and facilitate their incorporation into the design phase. Additionally, to extract design requirements suitable for analysis with heatmaps, we introduce the 4R concept to delineate the characteristics of these requirements.

    Compatibility of fire safety design specification of buildings to the requirement by the Building Standard Law (BSL) does not necessarily guarantee the avoidance of large fire loss occurrences. Development of a performance ranking framework is necessary for inducing buildings to maintain the fire safety performance higher than the level required by the BSL. In this study, we developed a novel framework for evaluating the fire safety performance of buildings by introducing the risk concept into the performance ranking system.

    Fire whirl is a tornado-like vortex of flame associated with urban fires, which would cause extensive human and property damages if occurred. However, to date, the occurrence condition of fire whirls has not been fully investigated. The issues that have been addressed in this study are as follows: 1) development of a statistical model for the post-earthquake ignition probability considering inter-earthquake heterogeneity; 2) development of a similarity model for the temperature field downwind of a fire source in cross-wind for reducing computational cost of fire spread simulation; and 3) wind tunnel experiments for investigating the occurrence conditions of fire whirls. These results can be used to evaluate the occurrence probability of fire whirls in contemporary cities by integrating them into the fire spread simulation.

    Extent of fatality due to natural disaster depends largely on spatial distribution of population at the moment disaster occurs. In this study, a computational model for estimating day-long spatio-temporal distribution of population is developed using a number of country-wide statistical data. The model estimates behavior of individuals by considering their attributes including age, gender, occupation, place of work, and place of residence. As a case study, the model is applied to the Keihanshin metropolitan area. Estimated maximum number of commuters unable to return home in an expecting earthquake scenario was between 1.1 and 1.9 million depending on the assumptions on traffic disruption following disaster. The model is also applied to the Kesennuma city which is struck by the huge tsunami at the occasion of the 2011 Tohoku earthquake. The result showed that the number of people in the tsunami inundated area ranges between 23,500 and 26,000 depending on the time of its occurrence.

    This study analyzes the applicability of paragraph 3, article 42 of the Building Standard Law for the preservation of historic alleys. Reduced scale experiments on heat transfer within an alley in case of fire and temperature-rise under an eave were conducted in order to investigate the behavior of fire spread between buildings. For the improvement of the fire spread simulation, critical condition for fire spread from a fire room to adjacent room was investigated by a compartment fire experiment. As for the fire risk assessment, questionnaire survey for post-earthquake ignition following the Tohoku earthquake was conducted and a probabilistic model was developed. Requirement of the present regulation was analyzed from the perspective of fire spread risk and evacuation safety. Survey on construction type was conducted in Kyoto city and a model for estimating the ratio of buildings unqualified to the present regulation is developed with additional statistical data on houses and land use.

    The evaluation method for the risk of historical buildings located in densely-built urban areas was developed by using the physics-based urban fire spread model formerly developed by the authors. The new method is based on the Monte Carlo Simulation with the variable parameters on ignition following earthquake, fire-fighting activity, structural damage due to seismic motion, and weather. With the new method, effectiveness of measures for fires following earthquake applied to the actual historical buildings was analyzed and the points of improvement were discussed.

    A new urban fire spread model which is greatly improved in computation speed than the existing physics-based urban fire spread model was developed byreplacing the method to solve time differential equations for building fire conditions with a method to solve algebraic equations for quasi-steady state of fire conditions. An urban residents? evacuation model for post-earthquake fire scenario was developed assuming that a suffered area is a potential field on evacuation hazard which is formed by the hazard level due to fire induced plumes and the psychological orientation to safe refuge of city residents. Combining the two models, a model for predicting urban residents? evacuation in case of post-earthquake scenario was developed. A user-friendly support system for assessing urban residents? evacuation risk was constructed aiming to helppractitioners with predictions of urban residents? evacuation in post-earthquake fires.

    Enhancement of fire safety performance and conservation of historical cityscape of a group of traditional wooden houses was simultaneously sought by reinforcing exterior walls at the boundary of two building sites among the "machiya"-type city block called "kozakai". In order to verify effectiveness of the fire safety measure such as sectional replacement of building component instead of refurbishment of entire building, urban fire spread model formerly proposed by the authors was refined and its user-interface was developed by integrating the model with GIS (Geographical Information System).

    本研究では,市街地の火災安全性能に対する合理的な評価を行うため,都市火災の延焼性状を,現象の物理的知見に基づいて定式化した.延焼モデルは,建物内部の火災性状予測モデルと,建物間の火災拡大性状予測モデルの二つのモデルから構成される.このうち前者については,建物内の各室を火災性状の検査体積とみなすゾーンモデルを拡張したものを利用した.後者については,火源からの輻射熱伝達,火災気流による温度上昇,火の粉の飛散を延焼要因として考えた.
    なお,延焼モデルを構成する個別の現象については,開口噴出気流性状に関するサブモデルを区画模型実験の結果をもとに定式化した.また,火の粉の飛散性状については,正方形平板の飛散シミュレーションを数値流体力学的手法に基づいて行い,この結果をもとに相似則を導いた.
    本延焼モデルの妥当性については,建物単体の火災性状を調べた既往の実験結果,ならびに酒田市大火(1976)での観測結果との比較を行うことで検討を加えた.このうち前者については,区画を隔てる扉や壁の燃え抜け時間を調整することで妥当な一致が得られた.一方,後者については,市街地において帯状の燃焼領域を形成しながら火災が拡大するとの定性的な傾向は一致する結果が得られたものの,延焼速度は全般的に過大評価された.
    さらに,ここまでに構築した延焼モデルを利用し,伝統的建造物群保存地区に指定される高山市三町地区を対象とした延焼シミュレーションを行って,市街地が有する火災リスクの評価を行った.伝建地区という性格上,火災安全性能を向上させるにあたって市街地の大規模な改変を加えることは困難であることから,建物の部材レベルの防火性能を向上させることで市街地全体の火災安全性能を向上させることを考えた.こうした場合の延焼シミュレーションを行った結果,市街地の火災リスクが低減される結果が得られた.
