ABSTRACT
In this study, the nonlinear static (pushover) and nonlinear dynamic procedures in the determination
of maximum displacements of an existing steel structure retrofitted with different methods have been
compared. These methods include the use of the EBF systems; RC Shear Walls and the use of
Passive energy dissipators such as metallic, viscous, viscoelastic and friction dampers. In nonlinear
dynamic procedure, the response of the structure to seven scaled earthquake records has been
obtained and the average value of the responses is used for comparison. At the same time in nonlinear
static procedure, the maximum displacements of the structure in two different load distribution
patterns have been obtained. The results demonstrate that the nonlinear static procedure determines
the maximum displacement of the structure conservatively.
