Abstract

Using ANSYS / LS-DYNA to study the dynamic response of square steel tube beam filled with steel-reinforced high-strength concrete under impact loading at different speeds. The numerical simulation results show that: At different conditions of speed, the concrete failure modes are different. The combined action of Steel tube and steel flange makes the stress wave propagation extremely complex in the beam, when the speed increased to a certain value, it made damage to the internal steel flange and flange lateral concrete under impact load, while the concrete between the top of steel flange and steel tube was protected by the combined action.
