Study on concrete at high temperature in China—an overview

Based on the investigation and review of experimental studies in the past 20 years in the People's Republic of China, this paper engages in further discussion and comparative analysis of researches on the mechanical behavior of concrete both under and after high temperature exposure. The following three aspects are focused on. First, the basic mechanical behavior of concrete at high temperature, including strength, elastic modulus, peak strain and Poisson's ratio. Second, the effect of high temperature on the yield strength and elastic modulus of rebar. And last but not the least, the high temperature response to the bond behavior between concrete and rebar. This overview summaries the states-of-the-art studies on the mechanical behavior of concrete at high temperature in China.
