Моделирование прогрева конструкций из автоклавного ячеистого бетона в условиях пожара
Ключевые слова:
огнестойкость, автоклавный ячеистый бетон, экспериментальные исследования, теплопроводность, разрушение, усадкаАннотация
Разработаны соответствующие методики и проведены экспериментальные исследования по моделированию прогрева конструкций из автоклавного ячеистого бетона в условиях пожара. Результаты теплового моделирования и испытаний теплофизических характеристик позволили оценить теплоизолирующие свойства исследуемых конструкций при пожаре. Получены экспериментальные данные поведения и прогрева тонких ячеистобетонных стен толщиной 120 мм с элементами жесткости из стальных профилей при пожаре. Разработана численная конечно-элементная модель, описывающая характер локального разрушения стены.
