The performance deterioration of concrete by high temperature provokes deformation of important structural materials like the column. Eventually, it brings collapse of construction. The deformation of column is caused by many factors like load, thermal expansion and creep, and These factors change as temperature changes. Therefore, It is very difficult to estimate behavior of concrete structure by fire and fire performance design. Furthermore, even though Japan, Europe and America have been doing various experimental studies on the properties of concrete at high temperature to solve these problems, Different results would be evaluated following to the heating method, heating time, size of specimen and performance of the loading and heating machine because there is no unified experiment method. Thus, this study is to represent heating and loading machine and experimental method which is developed in this study in order to identify analysis of behavior, improvement of fire performance design and experimental method of the properties of concrete at high temperature. This research is to present basic data on the properties of concrete at high temperature by reporting the result of this study. |
