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.
