Проведен анализ литературных источников по вопросу влияния горизонтальных проемов в горящем помещении на параметры пожара. Показаны ограничения по использованию ранее полученных результатов исследований при моделировании пожаров. Для предварительной оценки влияния горизонтальных проемов на температурный режим пожара в помещении проведено моделирование горения древесины в административном помещении для случая наличия только вертикального дверного проема и для присутствия дополнительных горизонтальных световых проемов. По результатам моделирования установлено существенное влияние горизонтальных проемов на температурный режим пожара в помещении и отсутствие методик, позволяющих в достаточной мере оценить влияние проемов в горизонтальных ограждающих конструкциях на интегральные теплотехнические параметры объемного свободно развивающегося пожара в помещении. Предложена доработка алгоритма расчета, использованного при разработке методики СТБ 11.05.03.
