公路混凝土梁式桥抗震性能鉴定

Study on Seismic Performance Identification for In-Service Highway Concrete Beam Bridge

基于公路桥梁抗震设计细则,借鉴国内外现有建筑和铁路抗震鉴定规范,将基于模糊层次分析法的公路梁式桥震害预测方法引入初步筛选的工作中,分初步筛选、一级鉴定和二级鉴定3个步骤,提出适用于抗震设防加速度为0.05g、0.10g、0.15g、0.20g、0.30g和0.40g地区公路混凝土梁式桥抗震性能鉴定的流程建议,并给出桥梁抗震鉴定记录的报告格式,对鉴定过程及结果进行记录。

Based on Highway Bridge Seismic Design Conditions, and existing buildings and railway seismic identification codes home and abroad and highway bridge seismic performance assessment and seismic strengthening technical guide used for reference, this paper introduces the highway girder bridge seismic damage prediction method which is built on the basis of fuzzy analytical hierarchy process into preliminary screening work, classifying three steps such as preliminary screening, identification I and identification II. Then, it puts forward some suggestions for the highway concrete beam bridge seismic performance identification, which is suitable for the area where seismic accelerations are 0. 05g /0. 10g / O. 15g / 0. 20g / 0.30g and 0. 40g. Finally, it provides the report format of the bridge seismic appraisal record, which is used to write down the identification processes and results.
