dynamic response - Opis:
- In this study, refined finite element models of concrete filled steel tubular long columns with length diameter ratio (L/D) of 50 were established, and their dynamic responses under a rigid-body impact were explored. It is found that the form of impact load is only related to and can be predicted from the impact velocity of the rigid-body. The change of axial stress and strain with time is synchronous with that of the impact load. Furthermore, the variation characteristics of axial stress and strain with time are mainly related to the initial velocity of the rigid-body.
