Abstract:Structural identification with incomplete input information is reviewed, and the multiple inversion method based on the least square method is further studied. Based on the statistical average approach, a new weighted average approach for the multiple inversion method is put forwarded. Further more, for structures with more than one correction condition, combined with the compensation approach, a new approach called mixed correction identification method is proposed. At last, as numerical example, a truss bridge with unknown ground motion is identified and the results show the effectiveness of the proposed method.
