摘要
主要阐述了中国-欧洲-摩洛哥抗震设计方法,从抗震设防目标、建筑结构重要性类别划分、场地类别、反应谱曲线、设防目标设计方法等方面对比了三个国家的抗震设计方法。通过摩洛哥具体超高层项目案例,对中国-欧洲-摩洛哥三本规范的地震反应谱进行了对比分析。分析结果表明:EC8抗规地震影响系数在下降段的衰减比RPS2011抗规和10抗规要快地多,在结构周期T=5.6s时,RPS2011抗规的计算结果略高于10抗规上海中震水平。中国-欧洲-摩洛哥三本规范在摩洛哥均有使用,且存在相互参考借鉴的情况,中国工程师应从宏观的角度进行概念把控,综合考虑当地标准及相关国际标准。
The seismic design methods of China-Europe-Morocco were mainly expounded. The seismic design methods of the three countries in terms of seismic fortification objectives, classification of building structure importance, site categories, response spectrum curves and fortification target design methods were compared. Through the case of a specific super high-rise project in Morocco, the seismic response spectrum of the three codes of China-Europe-Morocco was compared and analyzed. The analysis results show that the attenuation of the seismic influence coefficient of the European seismic code EC8 in the descending section is much faster than that of the Moroccan seismic code RPS2011 and the Chinese seismic code. When the structural period T=5.6 s, the calculation result of the Moroccan seismic code is slightly higher than that of Shanghai under the seismic precautionary intensity. The three specifications of China-Europe-Morocco are all used in Morocco, and there is a situation of mutual reference. Chinese engineers should control the concept from a macro perspective, comprehensively consider local standards and relevant international standards.
