4. C modeling#
This modeling provides a reference for test EPX bm_str_lcab_glis_amor which validates the effect of the sliding cable on concrete by reproducing tension in EPX. The Code_Aster reference is calculated with DEFI_CABLE_BP and CALC_PRECONT.
Test EPX bm_str_lcab_glis_amor uses EPX damping.
It uses both LIRE_EUROPLEXUS without going through CALC_EUROPLEXUS to retrieve the result of the test EPX contained in a file MED (given in unit 19) and reproduces the calculation with CALC_EUROPLEXUS.
4.1. Boundary conditions and loads#
Aster_code:
Same boundary conditions as modeling B. Prestress loading differs only on the initial tension value given by TENSION_INIT. Here it is equal to \(2.37182E+08\).
The value of this voltage is obtained from the component \(\mathit{DY}\) of the node ANCR2 on the field FLIA (bond forces) of EPX at the final moment of the calculation. It is the force induced by the imposed displacement applied to the concrete.
EPX:
Same boundary conditions and loading as modeling A.
4.2. Details#
As already said, in calculation EPX, damping functionalities are used to simulate a quasi-static calculation and thus obtain a stabilized solution in a reasonable amount of time.
We stop the calculation at \(0.2s\) by making sure that nothing changes anymore.
4.3. Tested sizes and results#
These tests have a reference AUTRE_ASTER given by the result from CALC_PRECONT.
