Abstract:
This article presents numerical and experimental study on the postfire behavior of concentrically loaded slurry-infiltrated fibrous concrete (SIFCON) columns after being exposed to flame from four sides for 2 hours while evaluating the effect of some testing parameters including column section type (solid or hollow), hollow section ratios of 25 and 50%, and the shape of the column section (square or circular). The first part is an experimental work to ensure that the model developed is adequate while the second part is a three-dimensional (3-D) finite element modeling of the SIFCON columns with the program ABAQUS using a sequentially coupled thermal displacement analysis. The test results indicated that SIFCON columns lost approximately 47 to 55% of their bearing capacity after fire exposure at 900°C and with 2 hours fire duration. Increasing the hollow ratio of the cross section is shown to decrease the postfire behavior of SIFCON columns. Moreover, the SIFCON columns with circular cross section exhibit higher values of ultimate load-carrying capacity than the square SIFCON columns with the equivalent cross-sectional area prior to and later after fire exposure.
