| Abstract: | The effect of the steel bar type and the heating temperature on the mechanics performance of steel bar was experimentally investigated. And the mechanics performance of deformed steel bar cooled down from high temperature was also tested. All the test results were compared with the relevant ones in room temperature. The decreasing degree of strength was got. This may be beneficial to the assessment and appraisal of RC structures after fire. |
