โœฆ Synopsis

This paper deals with applications of random uncertainty models in active control and structural optimization. Uncertainties are modelled via random ยฎelds that account for ยฏuctuations of the physical properties of the structure around the mean that is conversely deterministic, i.e. we adopt a pretty conventional approach. Unconventional are conversely the applications proposed. They extend classical results and tools in stochastic optimal control and structural optimization to systems aected by uncertainties. A stochastic-based concept of optimality is set forth and the proposed designs are optimal with respect to this newly established criterion. Numerical studies on MDOF systems and generally orthotropic plates complete the paper validating its theoretical derivations.

This work addresses certain aspects of shape optimization for linearly elastic systems in the presence of uncertainty. The goal is to formulate and test a set of computationally tractable methods for incorporating uncertainty in the system. The boundary element method is employed in solving the unde

This paper proposes an integrated approach to the modelling and optimization of structural control systems in tall buildings. In this approach, an artificial neural network is applied to model the structural dynamic responses of tall buildings subjected to strong earthquakes, and a genetic algorithm
