摘　　要：针对7度(0.15g)、8度(0.30g)区Ⅲ、Ⅳ类场地条件下结构的抗震设计,通过对《建筑抗震设计规范》(GB 50011-2010)有关设计要求的分析,探讨抗震措施和抗震构造措施时所应考虑的烈度以及采用的抗震等级,强调工程设计人员应注意的若干问题,如准确区分"抗震措施"和"抗震构造措施"的范围,按照调整后的烈度确定相应的抗震等级;指出规范中的一些值得商榷之处,如乙类建筑的抗震等级,调整后烈度超过9度时抗震等级的确定。Focused on the seismic design of buildings in class 3 or 4 site of 0. 15g or 0.30g region, based on the analysis and comparison of the relevant provisions in the code for seismic design of buildings （GB 50011-2010）, the intensity and the anti-seismic grade which affect the seismic measures and the details of seismic design are discussed. It should be emphasized that the difference between the seismic measures and the details of seismic design must be clear, and the anti-seismic grade must correspond to the adjusted intensities. Some arguable problems are pointed out, such as that the anti-seismic grade of class B buildings is still ambiguous, that the anti-seismic grade cannot be determined if the adjusted intensity is higher than 9.
