Abstract
In recent years, current seismic codes started contemplating the design of structures
with passive energy dissipating devices. One important issue for the rational seismic
design of these devices and the structure that contains them is the formulation of
methods to estimate their design seismic forces. From the study of the dynamic
response of single-degree-of-freedom systems subjected to accelerograms recorded
in Mexico during the last two decades, expressions to estimate the strength reduction
factor that should be used to reduce the elastic design strength spectra for 5 percent
damping, to establish the design seismic forces for structures having different
combinations of plastic and viscous energy dissipating mechanisms, are formulated.
