...Khaled Ahmed Mahmoud Purpose In literature, previous studies have focused on analyzing rienforced concrete (RC) columns with idealized end conditions when subjected to fire. In nature, full fixity or free rotation at column ends is not attained. Such ends may be considered partially restrained...

... N_u – M_u interaction diagrams of RC columns exposed to elevated temperatures. Their model, which account for the slenderness effect because of fire damage, adopted the 500°C isotherm method presented in Eurocode 2 (2004) . In addition, the maximum axial capacity was limited...
