the simulation results are not in agreement well with the tested results in strong ground motions excitation
A 3-Dimentional concrete frame strutural model is simulated and analzed adopting OpenSee program based on nonlinear beam-column fiber elememts.The simulation behaves well in the small and moderate earthquake intensity levels. However, the numerical simulation are not in agreement well with the experiment results when the stuctrue subjected to strong ground motions excitation. How is the result induced? please give a hand, thanks.
