    With regard to fire protection for exterior walls of a building, only ‘fire-resistive performance’ is considered, according to the current building standard law of Japan. And, fire propagation along combustible material installed at external side of fire-resistive wall is not specifically evaluated, even though combustion of external cladding could cause acceleration of the fire propagation along exterior walls, in some cases. In this study, new test method for evaluation of fire propagation along combustible cladding, was proposed and also, test specimens produced referring to façade wall with exterior thermal insulation were burned in order that the application of the method is demonstrated.

    Although timber is a combustible material, the char layers created on the surface during fires prevent further burning of the inner sections. Taking advantage of this feature, steel-timber composite (a steel plate sandwiched with timber using high strength bolts) section members were developed, expecting steel alone to take the load under fires. In this research, their 45-minute quasi-fire resistive performance was experimentally evaluated applying the standard time-temperature relationships. In the composite sections, the connecting bolts are exposed, which is not influential to the temperature elevation of the steel. The test parameters in the multiple test specimens were the section sizes as well as exposure of the side surface of the steel plates. The maximum steel temperatures in most specimens were below 350 Celsius.

    Investigation of fire load in 6 school gymnasiums, 2 for each of elementary, junior high and senior high schools in Akita and Fukushima Prefectures, is conducted for the performance oriented fire safety design of school gymnasium buildings under the localized fire concept. It reveals notable insufficiency of storages for exercise equipments which results in the increase of fire load in arenas and may make the localized-fire to achieve. A guideline has been proposed to prepare sufficient storage spaces in school gymnasium buildings.
