A. Nurtug et H. Sucuoglu, PREDICTION OF SEISMIC ENERGY-DISSIPATION IN SDOF SYSTEMS, Earthquake engineering & structural dynamics, 24(9), 1995, pp. 1215-1223
A simple analytical procedure is developed for calculating the seismic
energy dissipated by a linear SDOF system under an earthquake ground
excitation. The ground excitation is specified by its pseudo-velocity
spectra and effective duration whereas the SDOF system is defined by i
ts natural period of vibration and viscous damping ratio. However, the
derived relationship for the energy dissipation demand under an earth
quake excitation is sensitive neither to the viscous damping ratio nor
the ductility ratio when the SDOF system undergoes inelastic response
. Accordingly, the proposed relationship can be employed in an energy-
based seismic design procedure for determining the required energy dis
sipation capacity of a structural system.
