Abstract
the comparison of the reinforced concrete piles with steel rebars, FRP rebars under ship impact loading has been investigated by numerical modeling with the help of abacus software and considering the non-linear behavior of the materials and the geometry of the structure. Under the side impact, a vessel with a certain mass and speed is modeled under the same conditions.
Based on the results of numerical modeling, the following were extracted:
1- In the condition that both the rebar and the ties are steel, the damage is less at the place where the float collides with the concrete base, but the energy transfer and displacement of the energy waste in other parts of the pile away from the place of the float and the relative stress and strain change are greater. falls That is, in a concrete pile with completely steel components, power transmission (stress and strain occur more)
2- In a concrete pile with steel rebar and composite ties or fully composite components, the stress and strain and finally the local destruction of the structure is relatively higher, but the transfer of stress and strain to other components is less.
3- Most of the transfer of stress and strain to other areas is moved by ties, and the effect of steel and composite rebar is almost similar and insignificant
