Simulating the Unthinkable: How Abaqus Models the Chaos of an Earthquake
Concrete Damage Plasticity (CDP):
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.
- Max roof drift = 1.2% (acceptable per ASCE 7).
- Damage in columns at base (PEEQ = 0.025) – requires detailing.
- No uplift (tension in springs < weight/2).
Step 1: Build the FE model
Conclusion
Performing an earthquake (seismic) analysis in Abaqus involves simulating how a structure responds to ground shaking over time . This process generally falls into two categories: Response Spectrum Analysis for rapid, conservative linear estimates and Time History Analysis for detailed, time-dependent nonlinear behavior. 1.
