    Abstract
  • In order to study the continuous collapse behavior of reinforced concrete frame under impact load, the finite element model of reinforced concrete frame is established by ANSYS/LS-DYNA. The impact mass is 1 000 kg and the impact velocity is 4 m/s. The effectiveness of the numerical simulation is guaranteed by the verification of the of reinforced concrete members impact experiment and the frame collapse process. The analysis draws following conclusions: in the process of structure collapse of the mid column impacted, there is a mechanism of “arch effect” to “suspension effect”, the top of the middle column first goes up and then down, and the top of the side column first goes out and then inward; under the same impact load, the smaller the column axial force, the stronger column impact resistance and the column impact resistance is affected by different eccentric pressure. The impact resistance of reinforced concrete columns can be enhanced by infill column stirrups which can delay or even avoid the reinforced concrete frame structures continuous collapse.
