摘要：
The aim of this paper is the finite element modelling, updating and validation of the Uniovi Structure. This is a middle-size steel frame. The updating is based on natural frequencies, which are obtained from the free vibration of the structure. Three uncertain structural parameters are updated on the basis of the natural frequencies of two different configurations through an adaptive stochastic algorithm. Additional configurations corresponding to mass modifications were used to validate the updated model. It is found that the updated model can reproduce accurately the first two natural frequencies in all the configurations.
