【摘要】 抗震设防标准是一个国家抗震设防水平的综合体现。文中在详细研究日本、印度、土耳其、中国等亚洲8个国家建筑抗震设计规范的基础上,从场地分类、地震影响系数和设计地震反应谱几方面进行分析对比,探讨了各个国家的抗震设防标准差异。结果表明:亚洲场地分类数目为3~4类,其中宏观描述为划分类别的主要指标之一;实例计算表明中国和日本的抗震设防水平较高,韩国和土耳其的抗震设防水平较低。亚洲大部分国家建筑抗震设计规范中考虑场地条件的影响是通过调整地震动强度及地震动反应谱形状的方式来实现。文中分析结果对系统了解亚洲国家抗震设防水平具有重要的参考价值。更多还原

【Abstract】 Seismic fortification criterion is a national comprehensive reflection of seismic fortification level.In this paper,seismic design codes for buildings of Japan,India,Turkey,China and other 4 Asian countries are studied in detail.The seismic fortification criterions of these countries are compared through analyzing the site classifications,seismic influence factors and design seismic spectra.The results showed that the number of Asian site categories is 3 or 4.Macro description is one of the key indicators in site classification.The level of seismic fortification of Asian countries is different.Example shows that the level of seismic fortification of China and Japan is higher and South Korea and Turkey is lower.When considering site condition impact in design seismic spectral,it is realized through adjusting the ground motion intensity and ground motion response spectrum shape in most of the Asian countries building seismic design code.The exposition above has important reference value for understanding seismic fortification level of the Asian countries.更多还原
