Abstract: The February 6, 2023, M_w7.8 Turkey earthquake caused a large number of buildings collapsed. The near-fault unexpected strong ground motions have provided profound enlightenments and raised higher requirements for the revision of Chinese seismic design response spectrum. By comparing the response spectrum of actual near-fault records with the design response spectrums of China and Turkey, as well as the accumulative damage effect on structures caused by multiple strong earthquakes, the characteristics of strong ground motion in this earthquake were systematically analyzed, and the reasons of serious damage and collapse of buildings were clarified. Based on strong motion records from intensity IX and X zone of Turkey Earthquake, least squares fitting was used to calibrate spectral shape factors, and the characteristics of spectral parameters were analyzed and compared with those of seismic design response spectrum. The results show that: Spectral peaks of near-fault records are much higher than the highest level of design spectrum of China, the predominant periods of response spectrums are distributed in 0.1 s~0.5 s, and another obvious peak appears at about 1 s, the spectral value of 2 s~3 s is significantly higher than that of design spectrum of seldom occurred earthquake level in Turkey and China. Strong ground motions of peak horizontal acceleration exceeds 0.05 g, with a total duration up to 100 s, and cause accumulative damage to buildings. If this earthquake occurs in Chinese areas with earthquake fortification intensity of IX, the design response spectrum of site-class II and design earthquake-1st group during 0.55 s~2.30 s and design earthquake-2nd group during 0.70 s~2.80 s, will totally fail to meet the requirements for seismic fortification. The design value of β_max is lower than that of records from Turkey Earthquake intensity X, and the width of design spectrum platform is smaller than that of records from Turkey Earthquake intensity IX and X. This study suggests that the value of β_max and the width of design spectrum platform should be increased to fit high intensity ground motion.
