Abstract

 This paper reports on an experimental study regarding the behavior of restrained high-strength concrete in response to the type of extreme heating associated with fire. This study was intended to support estimation of thermal stress from the strain in a restraining steel ring and vapor pressure in restrained concrete under the conditions of a RABT 30 rapid heating curve. Thermal stress calculation was based on thinwalled cylinder model theory. It was also suggested spalling failure model was based on strain failure model. In a results, the model can be estimated the point at which the spalling started and spalling depth during heating.
