STRESS-STRAIN CURVES OF CONCRETE AT HIGH TEMPERATURE - A REVIEW

Baldwin, R. and North, M.A., 1969. STRESS-STRAIN CURVES OF CONCRETE AT HIGH TEMPERATURE - A REVIEW. Fire Research Notes 785


ABSTRACT

This note reviews some data on the effect of temperatures (up to 700C) on the relationship between stress and strain for concrete under compression. It is shown that if all the data are normalised to the stress and strain at the peaks of the various stress-strain curves for different temperatures (the compressive strength) the curves are virtually the same.
