RUIZ GARCIA, Jorge  e  GONZALEZ CUEVAS, Erick Jafet. Observations about the Code Criteria for Estimating Inelastic Displacements in Framed Buildings Located on Soft Soil Sites. Ing. sísm [online]. 2015, n.93, pp.20-40. ISSN 0185-092X.

This paper presents the results of evaluating the 2004 seismic code criteria to estimate lateral displacements in buildings. For this purpose, the elastic and inelastic displacement demands in 10 buildings having moment resisting frames as lateral structural system through rigorous nonlinear time history analyses. Results show that there is a spectral region where elastic displacement demands are larger than inelastic displacement demands which is not recognized in the 2004 seismic code criteria. It is also shown that the current criterion for estimating lateral displacements for service conditions included in Appendix A leads to reasonable estimations.
