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是衡量建築物室內所容納可燃物數量多少的一個參數,是研究火災全面發展階段性狀的基本要素。簡單一點,就是建築物容積所有可燃物由於燃燒而可能釋放出的總能量。在建築物發生火災時火災荷載直接決定著火災持續時間的長短和室內溫度的變化情況。因而,在進行建築結構防火設計時,很有必要瞭解火災荷載的概念,合理確定火災荷載數值。南京睿督公司免費諮詢電話:+86 25-86583475
