Simplifications and theoretical assumptions are usually incorporated into the numerical modeling of structures. However, these may reduce accuracy simulation results. This problem has led to development model-updating techniques minimize error between experimental response modeled structure by updating its parameters based on observed data. Structural models typically constructed using a determ...

Introduction Finite Element (FE) model updating entails tuning the model so that it can better reflect the measured data from the physical structure being modeled [1]. One fundamental characteristic of an FE model is that it can never be a true reflection of the physical structure but will forever be an approximation. In other words, FE updating fundamentally implies that we are identifying a b...

The following study deals with the updating the finite element model of structures using the operational modal analysis. The updating process uses an evolutionary optimization algorithm, namely bees algorithm which applies instinctive behavior of honeybees for finding food sources. To determine the uncertain updated parameters such as geometry and material properties of the structure, local and...
