Abstract
Steel frames with masonry infill walls are common systems in the ordinary residential structures.
High stiffness value of the infill walls has significant effect on the behavior of structure, torsional
problem is the one them. A friction damper device can be used to minimize torsional effects in the
structure. Nonlinear analysis and modeling of the infill walls and the damper is done by
“Opensees” [1]. Results show that the presence of infill walls can lead to severe torsion increase
through the frame which can be solved by using friction damper device. This technique can
benefit the complete capacity of structure with minimum intervention in the structure and
architecture.
