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.
