Abaqus Earthquake Analysis [patched] -

For reinforced concrete structures, use the CDP model. It allows you to define different tension and compression recovery factors, capturing the "stiffness degradation" that occurs during cyclic loading.

Don't just request stress. Request Hysteresis loops (Force vs. Displacement) to check how much energy your structure is absorbing through plastic deformation. 4. Why Abaqus? abaqus earthquake analysis
