某大跨钢结构天桥安全性鉴定要点

APPRAISAL OF SAFETY ABOUT LONG SPAN STEEL STRUCTURE BRIDGE

以某商务中心大跨钢结构天桥工程的结构安全性鉴定为例,依据GB/T50344-2004《建筑结构检测技术标准》对天桥工程的结构构件进行抽样检测,同时参照GB50292-1999《民用建筑可靠性鉴定标准》和GB50205-2001《钢结构工程施工质量验收规范》对结构安全性进行鉴定分析,以钢结构构件安全性能检测鉴定的全过程来明确钢结构安全性鉴定的要点,对类似钢结构工程的结构安全性鉴定具有重要的参考意义。

Taking structural security appraisal of a long span steel structure bridge engineering of a business center for example, the sampling of the bridge engineering was inspected by Technical .Standard fot Inspection of Building Structure （B/T 50344-2004）,and the safety of the bridge engineering was analysed by .Standard Jot Appraiser of Reliability of Ciuil Building（ GB 50292-1999） and Code for Acceptance of Construction Quality of Steel Structure（ GB 50205-2001）, the main points of the security appraisal of steel structure member were cleared by the whole process of safety performance test, which could have an important reference meaning for appraisal security of the similar steel structural project.
