Abstract: The seismic design methods of China-Europe-Morocco were mainly expounded. The seismic design methods ofthe three countries in terms of seismic fortification objectives,classification of building structure importance,sitecategories,response spectrum curves and fortification target design methods were compared. Through the case of a specificsuper high-rise project in Morocco,the seismic response spectrum of the three codes of China-Europe-Morocco wascompared and analyzed. The analysis results show that the attenuation of the seismic influence coefficient of the Europeanseismic code EC8 in the descending section is much faster than that of the Moroccan seismic code RPS2011 and the Chineseseismic code. When the structural period T1= 5.6s,the calculation result of the Moroccan seismic code is slightly higherthan that of Shanghai under the seismic precautionary intensity. The three specifications of China-Europe-Morocco are allused in Morocco,and there is a situation of mutual reference. Chinese engineers should control the concept from a macroperspective,comprehensively consider local standards and relevant international standards.
