THE SPATIAL CONTINUOUS EARTHQUAKE DESIGN RESPONSE SPECTRA
Firstly, the fuzzy characteristics of site classifications were analyzed, the spatial distribution of two-dimensional membership function for 4 types of site was presented and the fuzzifying of the site classification was realized. Nextly, the continuous method of the site characteristic period and the two-dimensional graphs was provided; the result shows that the characteristic period distribution confirmed by this method corresponds with the equivalence chart of the characteristic period given in current earthquake resistance code. Finally, a continuity method of design response spectra is proposed based on continuous engineering application of continuous design response spectra are also discussed. Practice proves that the continuous design response spectra confirmed by this method realized the smooth transition of design response spectra corresponding to 4 types of site. It is more accordant with the reality of engineering sites which have the features of non-determinacy, fuzziness and variance. It also develops a new idea for consideration characteristic affections more reasonably, as well as determination seismic design response spectra and seismic action more objectively and scientifically.
