Abstract:

In this paper, L steel reinforced concrete special-shaped columns are established by the finite element analysis software ABAOUS and we simulate and analyze models in blast loads. The main purpose is to study the antiknock property of L steel reinforced concrete special-shaped column in the different thicknesses of steel bone. We change the thickness of steel bone to get the time-displacement curve of L steel reinforced concrete special-shaped columns in blast loads. On the basis of the study we draw the conclusion: the antiknock property of L steel reinforced concrete special-shaped column is better than L reinforced concrete column and with the increasing of the thickness of steel bone the antiknock property of L steel reinforced concrete special-shaped column has enhanced.
