    Abstract :

    The paper presents a numerical method for a non-linear system equipped with passive viscous fluid dampers (VFD) in attempts to improve seismic resistance. A mathematical model for the motion and a computational algorithm to find responses of the structure are proposed. Focusing on a steel structure which is a benchmark 20-story building designed for the SAC project for the Los Angeles, California, the numerical example analyzes the dynamic response of the building subjected to earthquake-induced ground motion and simultaneously passively controlled with VFD. Furthermore, the paper will provide a basis for evaluating the factors affecting responses of such a controlled system and therefore these responses are compared to an elastic structure without VFD, an inelastic structure without VFD, an elastic structure with VFD, and an inelastic structure with VFD.
