Synopsis This paper reviews some data on the effects of temperature (up to 7000°C) upon the relationship between stress and strain for concrete under compression. It is shown that the effects of temperature can be represented by an equation of the form σ/σmax = f(ϵ/ϵmax), where f is a functional form independent of temperature, and σmax and ϵmax are the values of stress and strain at the point of maximum stress, which vary with temperature. This scaling law is used to derive a relationship for the variation of the modulus of elasticity with temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
