Response of UHPC-Concrete Composite Structural Members Using Implicit and Explicit Finite Element Method

This paper investigates the response of UHPC-concrete composite structural members using implicit and explicit finite element (FE) methods. Both methods were prepared and conducted individually for the FE analysis under static loading condition. Results of the implicit and explicit analysis were compared to experimental results conducted in previous study. Both the implicit and explicit methods showed similar overall response with fair accuracy compared with the experimental results. In addition, the effective plastic strain obtained from the FE simulation was in good agreement with the damage cracking pattern in the experiment.
