摘　　要：美国规范在国际工程上应用比较多,因此对美国规范(ASCE 7—10)中混凝土结构体系的抗震设计方法进行了研究,主要包括地震设计反应谱、混凝土结构的地震作用计算和调整以及混凝土结构的侧移限值等,对ASCE 7—10的抗震设计理念进行了讨论,并与中国抗震规范(GB 50011—2010)进行了对比。研究表明与中国抗震规范相比,美国规范的抗震设计理念应用比较灵活,设计人员选择的空间比较大。The seismic design of building represents the principal and superiority of the codes,and also is the difficult point of structure design. American codes has important impacts on the international engineering. More and more engineers need to master the designing method of international engineering. So this paper analyzed the seismic design in ASCE7-10,including design response spectrum,and calculated the seismic load effect and story drift limitation. Compared with the Chinese code GB50011-2010,the seismic principle of ASCE7-10 is discussed. The results indicate that the seismic principal of USA codes is flexible compared to Chinese codes which will leave the designer more options.
