- Abstract:
-
The strong-motion records selection has a lot of influence on the analysis result of the earthquake resistant design,and has been become a hot issue in the field of earthquake engineering.On the selection of strong-motion records,details of the provisions codes are sketchy in the current seismicity,and then they are hardly carried out.Firstly,the concept of the EPA mean spectrum is proposed on the basis of strong-motion recordings database for the selection,combined with seismic zoning map.The shape of the EPA mean spectrum reflects the influence of site effect.Compared with the target design spectrum in the code,it's more reasonable and close to real records spectrum.Then,the selection results show that the matching degree has improved significantly,using the EPA mean spectrum as the target.The results using EPA mean spectrum would satisfy the regulation that the matching degree is less than 20% during the selection.Finally,the method of the EPA mean spectrum provide an innovative approach for the seimic design ground motin selection.
