Super-Element with Semi-Rigid Joints in Model Updating
Civil engineering structures usually consist of a large number of members connected by joints. The joints are fixed with different types of fasteners, and they provide a certain amount of flexibility towards the static and dynamic behavior of the structure. Model updating of such a structure in practice is to improve the substructures followed by the joint property identification. This paper presents a method to update a super-element model of such a structure. The parameter selection strategy of generic element is adopted and the joint stiffnesses are treated as generic parameters to be updated simultaneously together with other structural parameters. An experiment with a three-dimensional steel truss is studied to illustrate the efficiency of the proposed method.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
