Abstract: Structural model updating has evolved
as a multidisciplinary research subject. The problem is now treated as determining a
mapping from modal parameters to structural model ones, and the mapping is realized by
Kriging model originated in geological statistics. For a real steel structure, all modal
data are measured experimentally, some model updating experiments are carried out with the
aid of partially experimentally measured modal data. The experimental results indicate
that modal data derived from updated model well coincide with the experimentally measured
modal data, and show the complementary properties to neural network model updating method.
Keywords: structural model updating, kriging, mapping.
