    Abstract: Earthquakes prove that infill walls have a negative significant effect on concrete frame, e.g.,
soft-storey, short column due to partial infills, torsional effects due to irregular and unsystematic placement
infills and out-of-plane collapse. However, their influence still not taken in consideration, therefore, it is very
important to define the behavior of the infill panels in the seismic response. Steel or reinforced concrete frames
are currently used in buildings with infill panels which are generally ignored when analyzing the seismic effects,
the fact that infill panels were not covered in the design stage and also in analyzes had led to a significant
damage, e.g.: Al-Hoceima in Morocco-L’Asnam in Algeria and Pam in Iran. The interaction between frames and
masonry infill panels in the seismic analysis becomes imperative to avoid such damage, indeed, these infill
panels are not considered as structural elements in structural analysis even if they have a significant
contribution on the structures properties (stiffness, strength, ductility, energy dissipation capacity).
