Abstract

Abstract

Based on the finite element analysis software ANSYS/LS-DYNA,it was established some finite element models of multibarrel tube-confined concrete columns at different cross-section form,and was analyzed the dynamic performances of them under three typical blast action by the post-processing software LS-PREPOST.The results showed that multibarrel tube-confined concrete columns had a good performance in anti-explosion.The simulation results could provide some references for anti-explosion design and the reinforcement of multibarrel tube-confined concrete columns and the selection of the structure form.
