ABSTRACT
Space double-layer grids are the structures that are vulnerable to the progressive collapse phenomenon. So, some methods should be looked for space double-layer grids that change their collapse behavior from brittle to a soft and ductile. In order to improve the space double-layer grids collapse behavior by using force limiting devices and also to avoid buckling, in compression members the structure element will be changed into the ductile ones. Hence space truss ductility can be done by force limiting devices. In the present study the effects of a number of force limiting devices on the progressive collapse behavior improvement of these structures have been studied. The present study determines the extent to which the limiting devices increase the ductility and load-carrying capacity variation of the double-layer space barrel vaults grids considering their number.
