A finite element model updating method based on global optimization

Finite element model updating of a structure made linear elastic materials is based on the solution minimization problem. The goal to find some unknown parameters finite (elastic moduli, mass densities, constraints and boundary conditions) that minimize an objective function which evaluates discrepancy between experimental numerical dynamic properties. depends nonlinearly may have multiple local minimum points. This paper presents method able global point assess its reliability. has been tested two simulated examples - masonry tower domed temple validated via generic genetic algorithm sensitivity analysis tool. A real case study monitored under operational conditions also addressed, structure's modal properties used in procedure estimate mechanical constituent materials.
