Seismic analyses of reinforced concrete structures are performed using the finite element method. A shake table test of a lightly reinforced concrete three story frame building and a shake table test of a seismically designed shear wall are simulated. The effects of modeling boundary conditions and of considering the initial micro-cracking of concrete on natural frequency change are investigated. These parameters are used to calibrate finite element models to experimental models. The simulations predict the overall seismic behavior of reinforced concrete structures. However, the analyses of both structures showed that accuracy of material degradation is lacking and the computational efficiency of such models needs improvement for large-scale seismic analyses.
