Abstract: Due to bad construction quality, a multi-story steel frame structure workshop needs detection and identification to evaluate the reliability level. According to the results of on-site detection and calculation analysis, the reliability level of the structure was determined according to certain standard. On the basis of detected safety hazard and construction deficiencies, considering as well as the effects of reliability, economy, feasibility and construction period, a strengthening design scheme was proposed. The strengthening construction was detected qualified and after the delivery all the factors fulfilled the requirements. The results indicate that the strengthening design scheme is reasonable and reliable.

Keywords: multi-story steel frame; detection and identification; strengthening design
