EXPERIMENTAL STUDY ON BEHAVIOUR OF TRICALLY COMPRESSED REINFORCED CONCRETE BERS UNDER DIFFERENT HEAT-LOADING PATHS

Twelve eccentrically compressed RC members were tested under different heat-loading paths. Different fire resistance properties of the members are reported under different heat-loading paths. An increment nonlinear algorithm is developed to calculate the behaviour of the specimens. The relations of temperature and curvature, load and curvature, and the ultimate load of the specimens are given, which are verified by the test data.
