摘要
主要研究某高架桥在发生火灾后,其承载力是否满足要求。首先对箱梁损伤状况进行了调查,并且对结构按原设计条件下、正常交通通行条件下和限行交通通行条件下不同工况进行了受力分析和对比,得出了高架桥各梁片跨中抗弯承载能力满足规范要求且有一定的富余度。为火灾后的相似结构在参数选择、受力分析计算方面等提供参考。
This paper is mainly to study whether the bearing capacity of viaducts can meet re-quirements after fire. At first,the damage status of box girders is investigated. And then force analysisand comparison of the structure is conducted under the original design condition,normal traffic con-dition and limited traffic condition and other different working conditions. And it is concluded that themid-span ultimate flexural capacity of beam pieces of viaducts are well enough to meet the standardsand requirements,and to provide reference for the preferences choices and bearing analysis and cal-culation of similar structure after a fire.
