Abstract: This study deals with the development of the knowledge about steel-reinforced concrete (RC) beams that are externally reinforced with textile reinforced concrete (TRC). During the last decades, TRC has been a subject of research, but few authors studied the use of TRC for a reinforcement of structural elements under fire or under combined elevated temperatures and mechanical loading. Reinforcement and protection of structures by a TRC solution under fire have got much potential but this subject is still not well studied. In this research, some aspects about the interaction between the TRC and reinforced concrete structure were numerically investigated in order to optimize the potential of TRC in fire-structural purposes.
