An interview survey was carried out on the hotel employees concerning the human behavior in a fire at Shirahama. The employees were interviewed about time interval from awaring unusual occurrence to evacuation start. The information obtained by the interview survey was arranged as the figure of the time series. The time axis of the figure refered survey of fire brigade and so on. Further, the figure which indicates the condition of fire, the propagation range of smoke and burnt odor and human behavior in initial fire was developed. As the summarization, it was clear why human evacuation was successful in this hotel fire.

In this study, with the aim of collecting the quantitative knowledge about radiant heat controlled by trees, the experiment was conducted using the ICAL radiant panel that can reproduce the radiant heating of constant intensity. By using this experiment, we considered the correlation of the shape of the tree and the shielding effect of the radiant heat of trees. As a result, shielding effect of radiant heat by camellia was confirmed by experiments. That effect was especially observed to have large tendency near the trees. Transmittance of heat flux and the shielding ratio(1-φy) have almost the same value, it was confirmed by the correlation of transmittance of heat flux and the shielding ratio(1-φy). Therefore, trees shielding ratio is one simple indicator that assesses the incident of heat shielding effect of the trees.

Glass panes used for fire protection windows has not only flame barrier performance but also parts requiring scattering prevention performance, crime prevention performance and impact resistance in the event of breakage of the glass in some cases, laminated glass is often used . In general, Poly Vinyl Butyral is used as the interlayer. Furthermore, in combination with Low-E glass which has become very popular in recent years, combined double glazing glass which has a radiant heat reduction effect is also used. Fire protection window with tempered fire resistance glass has passed the certification test based on know-how of each manufacturing company so far and has been adopted after various fire certification, but there are not standards for ensuring clear fire prevent performance. Regarding heated glass on fire, the test data was accumulated on the single glass, the insulated glass unit (IGU) and the Low-E IGU based on the fire test, and the thermal stress generated in the glass can be explained by grasping the temperature difference were revealed. However, the temperature properties of the laminated glass composed of the tempered fire resistance glass to be heated are not systematically clarified, and it is necessary to obtain basic knowledge. Therefore, in this study, considering the behavior of laminated glass and laminated IGU made of tempered fire resistance glass which is heated based on the knowledge obtained in the previous report. The fire test condition is shown below. ·These fire tests were performed for Laminated glass and Laminated IGU. ·Tempered fire resistance glass was mainly located on fire side. ·Fire tests were performed along the ISO834 Heat Curve for each specimen. ·The temperature of the glass was measured by thermo couples with a data logger. ·Surface Compression, Edge Cover of Glass, and Emissivity of Low-E glass were treated as parameters for heat stress of glass, ΔT and breakage factor of the glass were checked by fire tests. ·Laminated glass by heating is affected by the interlayer, its behavior is confirmed. Findings are as follows. (1) As the temperature difference between the glass surface and the edge increases, high surface compression stress is required. (2) The temperature difference between the glass surface and the edge increases as edge cover becomes deep, and the glass tends to break more easily. (3) The interlayer of the laminated glass foams and a layer of air is formed, and the temperature of the surface of the unheated side glass tends to be low. When the interlayer foams by heating, a foamed part and an unfoamed part are generated. (4) If Low-E glass is used in laminated IGU, the emissivity of Low-E glass influences the foaming time of the interlayer and the failure behavior of the unheated side glass. (5) Transmission of radiant heat flux of laminated glass and laminated IGU on fire was estimated.

A hotel fire occurred in Shirahama, Wakayama prefecture on November 17th1998. This building fire was one of the widest burning area of building firesin Japan. During this fire, there was high wind velocity at about Tin/sec. Atthe same time, there was a lot of number of fire brands. We surveyed thedistribution of fire brands and spot fires due to this fire by exploration andquestionnaire. As a consequence, it was found that through exploration andquestionnaire that there is a relation between the distribution of fire brandsand the size of fire brands etc.

建築物の性能的火災安全設計を行うためには、「設計火源(設計用入力火災)」を設定することから始まる。しかし、建築物内の可燃物の燃焼は、種々の要因により大きなばらつきがあって、告示式で与えられるように一義的なものではない。設計火源は、どのような可燃物を建築設計上考慮すべきか(用途区分別の特性的可燃物配置)という建築計画学としての整理を行った上で、特定された可燃物の燃焼性状を工学的にモデル化することが必要である。本研究においては、建築空間内に存在する可燃物の代表寸法と可燃物間の配置、壁面や柱等の建築要素との位置関係に注目して、建物用途、室用途の組み合わせ毎に、典型的な可燃物の配置パターンを作成すべきことを提案し、例題として事務所の廊下、教育施設の玄関ロビー、鉄道駅などの配置パターンを抽出してモデル化を行った。また、可燃物の燃焼性状に関しては、既往の文献資料を整理して、可燃物の一般的呼称毎に発熱速度曲線を集積して統計処理を行った結果、椅子、ソファ、クリスマスツリーなどの設計火源を提案した。これらを用いて、鉄道駅のプラットホーム構造物の耐火設計ケーススタディを行い、調査結果に基づき可燃物を想定し、燃焼性状の予測を行う標準的方法を提案すると同時に、現時点での知見で不足している点を指摘した。以上の成果は、(社)日本建築学会・防火委員会・火災安全設計小委員会の傘下に設置された「局所火災に対する耐火設計ワーキンググループ」との連携の下に行われ、シンポジウムを開催して成果を公表するとともに、建築設計者の意見を収集した。
