In this paper is studied the influence of the uncertain mass distribution over the floors on the choice of the optimal parameters of a hybrid control system for tall buildings subjected to wind load. In particular, an optimization procedure is developed for the robust optimization of a hybrid control system that is based on the Monte Carlo simulations and the genetic algorithm. The procedure allows to optimally design the control system taking into account the uncertainties on the distribution of the dead and live loads. With reference to a tall building modeled ad a multi degrees of freedom system, several numerical analyses are carried out varying the parameters which influence the distribution of the floors’ masses, like the variance and the correlation of the distribution over the floors.

Abstract
In this paper is studied the influence of the uncertain mass distribution over the floors on the choice of the optimal parameters of a hybrid control system for tall buildings subjected to wind load. In particular, an optimization procedure is developed for the robust optimization of a hybrid control system that is based on the Monte Carlo simulations and the genetic algorithm. The procedure allows to optimally design the control system taking into account the uncertainties on the distribution of the dead and live loads. With reference to a tall building modeled ad a multi degrees of freedom system, several numerical analyses are carried out varying the parameters which influence the distribution of the floors’ masses, like the variance and the correlation of the distribution over the floors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
