A Constitutive Material Model For Restrained Reinforced Concrete Columns in Case of Fire Part I
Özet
In the eighties increased basic research was carried out in SFB (SonderForschungsBereich: a special fire research activity for structural elements in Braunschweig Technical University, 1971-1986) in order to clarify the discrepancies between calculation and measurement of restrained compression elements in case of fire. The work was particularly focused on the description of a universal material model for the concrete under elevated temperatures that could be applied successfully to estimate the relaxation response of restrained compression col-umns in fire. In the literature, various material models for structural concrete can be found. In many cases, how-ever, the verification of such models lacks for the case of fire, especially when a mechanical restraining or caused by the entire structural interaction of the carrying system is present.
