SMOOTH SPECTRA OF HORIZONTAL AND VERTICAL GROUND MOTIONS FOR IRAN

摘要

In this study, several practical limitations of the current building code of Iran are addressed with respect to seismic hazard analysis (SHA) projects. The main concern of the present study is to propose a practical procedure for constructing smooth response spectra from the peak values of ground motion. The dynamic amplification factors are calculated for horizontal and vertical components, considering a selection of Iran's strong-motion records, and are compared with those proposed in the previous studies. The results and conclusions of this study are effective in the evaluation of the Iranian code and can be used in the SHA projects in Iran.
