Abstract
In this paper, the nonlinear finite element software ANSYS/LS-DYNA was employed to simulate blast re-sisting performance of FRP (fiber reinforced compite) pipe-concrete-steel pipe combination column.Failure modes of the combination column exposure to blast shock loading, dynamic response of the combination column at different proportional distances, and the ratio of thickness to diameter were analyzed.The results show that under explosive shock loading, dam-age degree of the combination column is obviously decreased; with the increase of the proportional distances, the peak value of the middle part displacement of all kinds of combination columns significantly reduced; with the ratio of thickness to di-ameter increasing, stiffness of the combination column gradually increased, and the displacement peak in the middle of the combination column is significantly reduced.It is concluded that the combination column has excellent antiknock perform-ance.It can provide reference for the further research with design of the FRP pipe-concrete-steel pipe combination column under blast loading.关键词
