Estimation of the seismic structural margins thanks to a numerical export and adaption, a non linear modeling of materials and time history dynamic analysis and push over analysis
The structure concerns the RHF building, protected by a containment chamber. Processing of the numerical model from HERCULE to Code_Aster. Achievement of the complete reinforced concrete building model. Walls and slabs are integrated in the model by multi-layer shells, beams and columns by multi-fiber beams. Non-linear material behavior laws : concrete (parabola-rectangle law taking into account of the traction limit, elasto-plastic with strain hardening steel).Dynamic non-linear time-history analyses. Non-linear push-over analyses for several seismic spectrums. Calculation of strength margins associated to the different seismic levels.
