✦ Synopsis
This paper describes a study whose primary intention was to determine how well state-of-the-art analytical/ numerical methods could predict the response of three shell structures in the service-level and strength-level regimes. Presented herein are the results of six ®nite element analyses, performed by dierent analysts of three, reinforced concrete shells. The shells were scale models of: an end-supported cylinder with edge beams; an end-supported, three-unit folded plate without edge beams; and a hyperboloid of revolution. The results of the analyses generally showed good agreement between predicted and measured displacements before cracking. Signi®cant dierences were noted between the dierent numerical results, and between numerical and experimental results from post-cracking to structural collapse. Nevertheless, it is concluded that the ®nite element approaches presented here can provide a suitable platform for the analysis and design of these shells if used by an experienced designer.
