ABSTRACT: Space double-layer grids are structures
that are vulnerable facing progressive collapse phenomenon. So some methods
should be studied for space double-layer grids that their collapse behaviors
change from a brittle one into a soft and ductile. Within this study, than of
these structures progressive collapse behavior has been studied. This study
answers this question that to which members early to take collapse of
double-layer space barrel vaults grids. This research can be identified with
the critical members of the progressive failure and overall structural damage
avoided.
