Abstract: In recent years, the number of steel structure engineering judicial identification cases increased year by year, but there was still not any technical standard of judicial identification specifically for steel structure engineering in our country. Several representative steel structure judicial identification cases was combined in this article, to analyze the difference between the steel structure engineering judicial identification and general detection and identification, the spot detection technology in the steel structure engineering judicial identification, the method and existing problem in the steel structure engineering judicial identification, and to summarize the method of spot detection and quality assessment in the steel structure engineering judicial identification. This article proposed the principle of spot sampling and the commonly used non-destructive detection method in the steel structure engineering judicial identification, exemplified common types of standards and identification methods in steel structure engineering judicial identification in practice, which can be offered to related personnel as a reference.
