| Abstract: | According to the physical characteristics of response spectrum period and the influence of dynamic characteristics of the structure,the selection method of ground motion is put forward,which is suitable for Chinese codes.The emphasis of the method is to control the characteristic period of ground motion response spectrum to be consistent with the characteristic period of standard response spectrum,and the Tg~6s period was divided into six fitting intervals and corresponding selection intervals.Moreover,three typical middle and high-rise buildings were selected to analyze the advantages and disadvantages of the new method based on the evaluation principle of China's standard time-history analysis of the base shear force.The results show that the new method was effective in selecting ground motion recordings and has strong applicability to the different structures. |
