Abstract:

© 2017, Editorial Office of Journal of Vibration and Shock. All right reserved. A 3D FE model was developed to analyze dynamic response and damage mechanism of a UHPSFRCFDST(Ultra-High Performance Steel Fiber Reinforced Concrete Filled Double Skin Steel Tube)column under blast loading, they were validated through comparison of simulated results and blast testing ones of the UHPSFRCFDST column. The effects of main variables including hollow ratios, steel ratios, and thicknesses and strengths of inner steel tube and outer steel one on the blast resistant performance of the UHPSFRCFDST column were investigated by utilizing the 3D FE model. The results indicated that the UHPSFRCFDST column has excellent anti-blast performances, and the proposed 3D FEM model can be used to analyze the dynamic response of the UHPSFRCFDST column under blast loading efficiently; reducing hollow ratio and increasing strength of outer steel tube in certain ranges can enhance effectively the blast resistant performance of the UHPSFRCFDST column; increasing steel ratio and reducing height to thickness ratios of inner and outer steel tubes can significantly improve the blast resistant performance of the UHPSFRCFDST column; the strength of inner steel tube has a little effect on the blast resistant performance of the UHPSFRCFDST column, but increasing the strength of outer steel tube in a certain range can improve the blast resistant performance of the UHPSFRCFDST column significantly.
