- Abstract:
- 320 strong motion records of four sites are appropriately selected.Based on energy equations of SD-OF system, the elasto-plastic dynamic analysis program is used to study the effects of characteristics of earth-quake motion on seismic energy response of SDOF system.The study results are obtained as follows;Seismicenergy response,hysteretic energy dissipation and damping energy dissipation increased with the increase ofearthquake magnitude.The medium length period structures subjected to minor shock are depended on damp-ing energy dissipation to consume the seismic energy.And,structures subjected to major shoek are dependanton hysteretic energy dissipation to consume the seismic energy.When the site soil softens,seismic energy re-sponse increases and its amplification also aggravates.Seismic energy spectra of other protected earthquake in-tensity can be obtained by adjusting seismic energy spectra of the standard protected earthquake intensity ac-cording to square ratio of PCA ( protected earthquake intensity ) to PCA ( standard protected earthquake).
