Degradation of concrete mechanical behavior due to temperature effects

Abstract

In this work, the capabilities of a material model to describe and predict the degradation of concrete capacity and mechanical behavior due to temperature effects are presented. The predictions of the numerical model are compared with experimental results of concrete subjected to different temperatures. The results in this work show the severe consequences of the long term exposure to temperature of concrete main features such as strength and stiffness and, in this sense, it is also shown the effect of this mechanical features degradation on the safety condition of the related structures. Moreover, the numerical results demonstrate the accuracy and capacity of the mathematical model proposed by the Authors regarding concrete structure behavior subjected to combined action of temperature and mechanical loading.
