Fire damage of concrete building structures

The authors proposed innovative approach to defining the extent of damage for concrete building structures. The present paper factors in the problems of detection of damaged structures arising due to thermal stress. The detection methods have been analyzed. There has been found and justified the need for elaboration of complex methodic applicable to detection of fire pocket and the evaluation of possibility of further structural use. The authors have shown the possibility of applying methods of synchronous thermal analysis for investigation of concrete composites with the purpose of further detection of hidden fire pocket and finding severely damaged members of building structures. The obtained results of synchronous thermal analysis are recommended for evaluation of further possible service of building structures.
