[關鍵詞] 鋼筋混凝土 火災 火災試驗 鋼筋混凝土 連續(xù)板A research about the full-scale three-span reinforced concrete continuous slabs with dead load under fire was carried out. The whole test made use of the self-made fire-test furnace which was reliable and convenient. From the test, the regularities of the deformation and the temperature distribution are presented, furthermore the characteristics of the internal force redistribution and their destroying features are analysed.
