Abstract

Masonry remains today an essential, even indispensable at buildings in Morocco, however,   the   lack  of   experimentation   led   to   the   neglect   thereof   in   digital computing  models  especially  the  panels  with  openings.  On  the  other  hand, damage  in  seismic  zones  showed  a  significant  participation  of  this  panel  on  failure modes. It is noteworthy that the Moroccan seismic regulations RPS 2000 Reviewed in 2011 advocates modeling masonry infill panels with two equivalent rods [cf. Art No. 7.3.3].
