Abstract

Abstract

In order to improve the blast resistant performance of prefabricated highway bridges, a precast segmental concrete-filled double-skin steel tube (PS-CFDST) column was developed. A large equivalent field blast test on the PS-CFDST columns was conducted and a high-fidelity finite element model was established using LS-DYNA to simulate the dynamic response and failure mode of the PS-CFDST columns under blast loading. The experimental and numerical results demonstrated that the failure mode of the PS-CFDST columns under large equivalent surface explosion was fracture failure of prestressing tendons induced loss of column integrity. The PS-CFDST column exhibited large shear slippage at the column bottom segment-to-footing joint. The damage to core concrete was concentrated at the joints and contact areas between segment and prestressing tendons. The modeling approaches for prestressing tendons have a significant influence on the dynamic response of the PS-CFDST columns. Increasing axial loads can effectively mitigate the column lateral deflection and shear slippage at the column bottom and it is beneficial to improve the blast resistance of the PS-CFDST columns.
