The paper presents some results on the influence of the pre-stress induced by the erection method in elastic grid shells on their buckling capacity. The numerical methods have been validated with the study of a pre-buckled arch. A form-finding scheme using low-speed dynamics has been employed to generate automatically a family of elastic grid shells. Their buckling capacity has been compared to the one of grid shells with the exact same geometry, but without any pre-stress. The paper demonstrates that the pre-stress decreases the buckling capacity of elastic grid shells.
