Abstract EN
Recently, a concrete-filled steel tube confined with fiber-reinforced polymer (FRP) has become a hot research issue as a new type of structure.
These studies mainly focus on its static performance and seismic and impact behaviour, with little research on its blast resistance performance.
In this study, the dynamic response of concrete-filled steel tube columns confined with FRP under blast loading was investigated.
Numerical analysis was implemented using multimaterial ALE method in the finite element analysis program LS-DYNA.
The proposed numerical model was validated by the SDOF result and available experimental data.
And the effects of the number of FRP layers, concrete strength, and cross section were also discussed in detail based on the proposed numerical model.
The results indicate that the constraints of FRP effectively enhance the blast resistance of the column, and the vulnerable parts mainly occur at the middle and two ends of the column.
The blast resistance of the column can be enhanced by increasing the number of FRP layers or concrete strength.
These results could provide a certain basis for blast resistance design of concrete-filled steel tubes confined with FRP.
