NFPA 557-2020 Standard for Determination of Fire Loads for Use in Structural Fire Protection Design
NFPA 557-2020 結構防火設計用火災荷載測定標準

火災荷載Fire Load是衡量建筑物室內所容納可燃物數量多少的一個參數,是研究火災全面發(fā)展階段性狀的基本要素。簡單一點,就是建筑物容積所有可燃物由于燃燒而可能釋放出的總能量。在建筑物發(fā)生火災時火災荷載直接決定著火災持續(xù)時間的長短和室內溫度的變化情況。因而,在進行建筑結構防火設計時,很有必要了解火災荷載的概念,合理確定火災荷載數值。南京睿督公司免費咨詢電話：025-86583475
