Abstract

In this work the general aspect and the behavior of a simplified theoretical model for studying mass isolated systems are investigated. The model is in the form of a dual mass model in a single storey arrangement. To find damping ratio and natural frequency of the system, Non-classical Eigen analysis has been performed on the model. Later, time integration analyses subjected to different earthquake records were carried out on the same model. In time integration analyses the model was equipped with linear, nonlinear and controllable viscous energy dissipaters. The results of Eigen analyses on the model show a limit point on the level of maximum achievable damping ratio in the system. According to the results of time integration analyses, using NONLINEAR VISCOUS DEVICEs in the system (instead of the linear one) reduces the sensitivity of the model to its design parameters (including damping constant) and provides the system with a practical optimal design solution. The results also show that, using viscous devices with controllable features in the model lead us to a system with higher level of structural performances.
