The detection and inspection of these structures have realistic inspection and guilding significance after fire. The procedure for evaluating fire damage to concrete structures was discussed using a burnt high-rise building as an example. The procedure includes the emergency investigation of the fire site, the estimation of fire temperature, the initial division of floors and areas based on the visual damage, and the inspection of burnt structural members. The concrete structures were evaluated according to the degree of fire damage they received as well as their characteristics. Lastly, rehabilitation measures for concrete structures were proposed based on their fire damage grades.Keywords: high-rise building; fire; concrete structure; damage evaluation; repair and reinforcement作者簡(jiǎn)介：翟傳明，教授級(jí)高工，Email: zhaichuanming@ceedi.cn。參考文獻(xiàn)［1］范進(jìn),呂志濤. 混凝土結(jié)構(gòu)抗火研究的主要內(nèi)容［J］. 建筑技術(shù),1999,30(5):319-320.［2］李耀莊,唐毓,曾志長(zhǎng). 鋼筋混凝土結(jié)構(gòu)抗火研究進(jìn)展與趨勢(shì)［J］.災(zāi)害學(xué),2008,23(1):102-107.［3］GB 50016—2006 建筑設(shè)計(jì)防火規(guī)范［S］.北京：中國(guó)計(jì)劃出版社,2006.［4］ASCE 29—05 Standard calculation methods for structural fire protection ［S］.Reston,2007.［5］EN 1992-1-2:2004, Eurocode 2: Design of concrete structures-Part 1-2: General rulesstructural fire design［S］.Brussels,2008.［6］李國(guó)強(qiáng),韓林海,婁國(guó)彪,等. 鋼結(jié)構(gòu)及鋼-混凝土組合結(jié)構(gòu)抗火設(shè)計(jì)［M］.北京:中國(guó)建筑工業(yè)出版社，2006.［7］韓林海,宋天詣. 鋼-混凝土組合結(jié)構(gòu)抗火設(shè)計(jì)原理［M］.北京:科學(xué)出版社,2012.［8］李敏. 高強(qiáng)混凝土受火損傷及其綜合評(píng)價(jià)研究［D］. 南京：東南大學(xué)，2005.［9］李敏,考宏濤,錢春香. 高強(qiáng)混凝土受火后損傷的模糊綜合評(píng)價(jià)［J］.混凝土,2008（6）:8-10.［10］方崇,韋慶輝,梁漢吉. 遺傳投影尋蹤回歸在火災(zāi)后高強(qiáng)混凝土損傷科學(xué)評(píng)價(jià)中的應(yīng)用［J］.四川建筑科學(xué)研究,2010,36(4):84-86.［11］王威,蘇經(jīng)宇,韓陽(yáng)，等. 火災(zāi)后混凝土損傷綜合評(píng)價(jià)的物元模型［J］.混凝土,2008（1）:20-22.［12］楊璇. “央視大火”原因調(diào)查［J］.勞動(dòng)保護(hù),2010（4）:36-39.［13］ISO 834 Fire-resistance test-elements of building construction ［S］.2008.［14］ANNEREL E, TAERWE L.
