【摘要】：一混凝土梁橋受大火燒損,損壞嚴(yán)重。文中給出該橋損傷檢測內(nèi)容及快速評定方法(基于頻率校驗系數(shù)法)�？焖僭u定方法準(zhǔn)確給出6個損傷等級。火災(zāi)后的主要損傷形式為混凝土表面爆裂、鋼筋彈性模量降低、結(jié)構(gòu)承載力降低。根據(jù)橋梁受損狀態(tài)給出相應(yīng)的快速修復(fù)方法,對類似橋梁受火災(zāi)后快速評定及修復(fù)具有參考價值。
[Abstract]:A concrete girder bridge was badly damaged by fire. In this paper, the contents of damage detection and the fast evaluation method (based on the frequency check coefficient method) are given. Six damage grades were accurately given by the rapid assessment method. The main damage form after fire is crack of concrete surface, decrease of elastic modulus of steel bar and decrease of bearing capacity of structure. According to the damaged state of the bridge, the corresponding rapid repair method is given, which has reference value for the quick evaluation and repair of similar bridges after fire.
