Abstract The numerical simulation for a new type of precast concrete barrier for viaducts
is carried out systematically. To obtain an accurate representation of the damage state of the
concrete barrier under the impact of a vehicle, a stochastic damage-plasticity model of the
concrete is adopted in the finite element model. Meanwhile, a simplified mathematical
model of the impact between vehicles and the concrete barrier was established and the
input energy was converted to the impact load to facilitate the investigation of the safety
performance of the concrete barriers. On this basis, a refined finite element (FE) model
of a precast… More >
