Abstract

Abstract: This study analyses the thermomechanical behaviour of steel-reinforced concrete (RC) beams strengthened with textile reinforced concrete (TRC) under mechanical and fire loads (i.e., the standard fire curve, ISO-834). Two main aspects are investigated. First, the effect of the TRC's thickness on the thermomechanical behaviour of RC beams is assessed. Then, the thermomechanical behaviour of RC beams strengthened with TRC is numerically modelled for different heating rates (i.e., heating scenarios). The results and conclusions of this study clarify the thermomechanical contributions of TRC to RC structural elements subjected to fire scenarios.
