Abstract

In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. SPECTRAL PARAMETERS of an earthquake convey a variety of information about ground motion, so they can properly characterize an earthquake. Also a lot of damage indices were proposed by researchers to quantify the damage of the structures or to rank their vulnerability relative to each other. PARK-ANG INDEX is one of the best indices to describe the damage of a structure. In this paper, the correlations between SPECTRAL PARAMETERS of earthquakes and Park-Ang indices are studied. Three RC frames with different height are analyzed under far-fault earthquake records by nonlinear dynamic analyses. The correlations between SPECTRAL PARAMETERS and Park-Ang indices of the frames are calculated. The results show that in all the frames most of SPECTRAL PARAMETERS have strong correlations with DAMAGE INTENSITY. In order to estimate the damage potential of an earthquake, some SPECTRAL PARAMETERS which have high correlations with DAMAGE INTENSITY can be proper indices. Housner intensity, acceleration spectrum intensity and velocity spectrum intensity are shown to have strong correlations with DAMAGE INTENSITY. In this paper, a new spectral parameter which has high correlation with DAMAGE INTENSITY is achieved.
