With the increasing use of high-strength concrete (fc > 60 MPa) in building construction, the risk of exposing these structures to high temperatures during a fire has increased significantly. To be able to assess the structural safety of such structures after a fire, it is important that the mechanical properties of the material be well assessed with regard to high-temperature effects. In this context, a study was conducted to investigate the residual mechanical properties of confined and unconfined high-strength concrete (fc = 70 MPa) after a ...
