Bridge piers are highly vulnerable to accidental collision with heavy truck vehicles. Current design and assessment codes account the effect of vehicle collision by means of an equivalent static load. This methodology although is simple but have raised many concerns on their suitability to reflect the exact collision condition, which is highly dynamic. Therefore many…
This paper presents a finite element (FE) modelling to predict the behaviour of ultra-high performance concrete (UHPC) members under static flexural loading. A plasticity-based constitutive model for concrete and an implicit solver in LS-DYNA were adopted in the numerical simulation. Experimental data for 21 UHPC specimens tested in the present study and in previous works…
In this study, an improved finite element (FE) model was developed for the prediction of the structural behaviour of reinforced concrete members strengthened with ultrahigh-performance concrete (UHPC). A concrete damage model and an implicit solver in LS-DYNA were adopted in the numerical simulation. The model was calibrated and validated using experimental data. Accurately representing the…
