Nonlinear thin shell finite element for steel and concrete structures subjected to fire: verification and validation

[en] This article presents verification and validation examples for a nonlinear thin shell element developed for structures subjected to fire. The verification benchmarks are: a Z-shaped cantilever, a twisted cantilever beam, a hemispherical shell, and Lee's frame at room temperature and at elevated temperature. The element shows that it provides results in good agreement with theoretical results and other finite elements. The validation calculations have been performed on an H rolled profile and a concrete slab. The element demonstrates its ability to reproduce local buckling on a H-steel beam under fire conditions and that it predicts accurately the failure of a concrete slab subjected to fire. The theoretical development of this finite element has been published in the Journal of Applied Fire Science, Vol. 11, No. 4, pp. 291-310, "Nonlinear Thin Shell Finite Element for Steel and Concrete Structures Subjected to Fire: Theoretical Development."
