ABSTRACT = {The properties of infills and the way they are connected to frames may
have significant effects on the seismic behavior of the structure. This study presents an experimental study on evaluation and testing of five single story, single
bay samples with the scale 1:3. This study strives to evaluate the behavior of
masonry infill walls encased in steel frames, with emphasis on different details
of the connection of the wall to the frame. Four frames with masonry infills
and one frame without infill are experimented on by applying lateral load to their
upper beams. Different details of the connection between the infill and the frame
including anchorless wall within the frame, connecting the frame and the infill
using separating vertical angles, steel rebars embedded in the infill wall and also
using Added Damping And Stiffness (ADAS) elements between the infill and the
frame were investigated. The results indicate that the manner in which the infill
and the frame are connected not only can significantly affect the crack formation
pattern and the failure modes of the infill wall, it’s also alters the stiffness, the
strength, the ductility, the out-of-plane deformation, and the amount of energy dissipation of the frame. Furthermore, not only using the ADAS yielding damper in
the connection between the infill and the frame increases ductility and prevents
the load-displacement diagram from plummeting, it also can be used in regions
with medium to high relative seismic risk given that it can be replaced after the
occurrence of earthquakes.},
