Determination of Active Force of Adjustable Active Mass Damper (ATMD) In Concrete Structure Using Z-Number

Abstract

In this research, in order to solve the difference between the values of the active force of the damper ATMD  in the case of using equations of motion and experiments, it is suggested to use z-number in fuzzy logic. The obtained results indicate that considering z-number causes significant changes in the output results of the active force so that it is closer to the real values. On the other hand, these results show that the existing equations of motion are not accurate enough and need to be modified and add coefficients. These results are consistent with previous articles and have been confirmed in other articles as well. Finally, it is suggested to the designers of this field to use the proposed process in order to increase the accuracy in active force calculations.
