By means of a graphical procedure, the
capacity spectrum method compares the capacity of a structure with the demands
of eartyhquake ground motion on it. In the present version of the method, highly
damped elastic spectra have been used to determine seismic demand. A more
straightforward approach for the determination of seismic demand is based on the
use of the inelastic strength and displacement spectra which can be obtained
directly by time-history analyses of inelastic SDOF systems, or indirectly from
elastic spectra. The advantages of the two approaches (i.e. the visual
representation of the capacity spectrum method and the superior physical basis
of inelastic demand spectra) can be combined. In this paper, the idea of using
inelastic demand spectra within the capacity spectrum method has been elaborated
and is presented in an easy to use format. The approach represents the so-called
N2 method formulated in the format of the capacity spectrum method. By reversing
the procedure, a direct displacement-based design can be performed. The
application of the modified capacity spectrum method is illustrated by means of
two examples [COBISS.SI-ID 756065]
