flexural behavior investigation of reinforced concrete member with strengthening using strain hardening cementitious composite

Strain hardening cementitious composite (shcc) is an attractive construction material for reinforced concrete (rc) structure strengthening, whereas the behavior of rc member with flexural strengthening using shcc has not been clearly understood, since it is affected by various complex factors. in this paper, an experimental investigation into failure behavior of rc member with flexural strengthening using shcc is implemented, which gives initial stage to the broad spectrum of the test. moreover, a calculation model is also proposed for predicting the load-carrying capacity of flexural strengthened rc member using shcc, in which the influence of varying shcc layer thickness is considered. the results demonstrate the cracking behavior of shcc layer is significantly affected by the varying shcc layer thickness. the comparison of calculated and experimental results confirms the effectiveness of the proposed calculation model for predicting the load-carrying capacity of flexural strengthened rc member using shcc.
