Abstract
Temperatures in protected steel structural exposed to fire significantly increase due to cracks or gaps in fire protection damaged by earthquakes or thermal deformation. In this study, a series of experiments was conducted to clarify the influence of a partial flaw in fire protection, such as cracks and joint gaps that emulate structural or thermal damage, on the temperature increase of the steel elements. A temperature prediction model for the steel elements with a flaw in fire protection was developed. The thermal invasion through the damage in fire protection was considered in the model and the estimation validity was clarified.
