Abstract
A non-linear static analysis with monotonically increasing lateral loads was
performed for two RC buildings with 6 and 17 stories, respectively, in order to
compare their response against the results obtained from inelastic seismic
analyses for the SCT-EW-85 record. The buildings are located in compressible
seismic zone IIIb, and are designed according to Appendix A of the Mexico City
Building Code (RDF-04), for a soil dominant period of Ts=2 seconds, satisfying
the maximum service and collapse limit states for story distortion. Resistances
were designed taking into account a three-dimensional structural performance in
addition to the vertical load effects and second order effects. Due to the use of
seismic performance factors (Q=4 for the 6-story building and Q=3 for the 17-
story building), and according to the Concrete Construction Standard, special
requirements were considered for the ductile frame. Nominal resistance and
over-resistance effects were considered for the non-linear responses. Different
inputs of lateral load patterns for the non-linear static analysis were taken into
account. The comparisons were performed for base shear force–roof lateral
displacement relations, global distribution of plastic hinges, failure mechanics
tendency, local and global ductility demands, etc.
Keywords: spectral modal dynamic analysis, non-linear static analysis, inelastic
seismic analysis.
