In order to explore the influence of high temperature on the dynamic and static mechanical properties of steel fiber reinforced self-compacting concrete (SFRSCC)the dynamic and static mechanical properties of SFRSCC at room temperature (25 ℃) and after heat treatment at different temperatures (200400600800 ℃) were testedand the numerical simulation analysis was carried out by combining LS-DYNA software and HJC constitutive model. The results show that the static compressive strength of SFRSCC increases first and then decreases with the increase of temperature gradeand reaches the maximum value of 66.9 MPa at 200 ℃. Under the same level of impact loadwith the increase of temperature gradethe dynamic compressive strength of SFRSCC increases first and then decreasesand reaches the maximum at 200 ℃. The dynamic compressive strength of SFRSCC increases with the impact load leveland the dynamic strength growth factor increases with the increase of strain rate. The failure modes of simulation and test are consistent.
