Abstract

En 中文

• The eigenvalue problem equation is embedded in the posterior PDF for its construction in reduced eigen space • Sub-structure parameterization gives a linear relationship between structural and modal parameters for efficient iteration • A sampling method combined with an enhanced iterative algorithm for constructing the posterior PDF • Effectiveness of the proposed method is demonstrated with simulated and full-scale buildings
