The correlation coefficient betw een the ductility of wt om asonry structures subjected to each group of ground motions and the corresponding groundmotion param etersw ere calcu lated. Then the analysis and comparison of correlation coeff-i cientsw ere conducted and the result mi plied that PGA, EPA, Einput, Eh can reflect the damage potential form a- sonry structures. And all these groundmotion parameters have good correlation w ith seism ic intensity and they can serve as the physicalmeasure of seism ic intensity.
