对比分析中国有关场地条件对设计反应谱最大值的影响
|
摘要
对国内有关场地条件对设计反应谱最大值影响的研究现状作了介绍,对不同研究者所采用的研究方法和得出的结论进行了对比。通过对比发现了4点不同:1)场地类别划分标准不同;2)所用地震记录来源不同;3)地震动强度的划分依据不同;4)在计算场地系数时所参照的场地类别标准也不同。同时,发现中国规范中Ⅳ类场地的范围过于小,有必要进行调整。综合上述分析,提出用峰值加速度来表示地震动强度,按照Ⅱ类场地的峰值加速度来进行分组,以有效峰值加速度EPA作为计算标准更加合理。利用真实的地震记录,根据各个台站的地质剖面图,按照中国现行的场地类别划分标准对所得到的场地进行类别划分,通过计算不同类别场地的EPA,结合这些分析结果,建议了用于不同类别场地设计反应谱最大值的一组经验系数。
The present situation of research on the effect of site condition on the maximum of design response spectra in China is introduced and analyzed in this paper.The methods used by various researchers and conclusions gained by them are contrasted,then differences existing in them are pointed out.Comparison of these methods shows the differences in four aspects,i.e.1)criteria for site categorization;2)origin of earthquake records used;3)basis for determining the ground motion intensity;and 4)site categorization standard referenced in calculating site coefficient.Meanwhile,we find that the range of the site category Ⅳ in Code for Seismic Design of Building in Chins is too small,so it is necessary to be adjusted.The above analysis and comparison indicate that it will be more reasonable to categorize the ground motion intensity with the peak ground acceleration of site category II and take the effective peak acceleration(EPA)as the calculation standard.In the end of this paper,categorization is done for the available sites based on the actual earthquake records,the current site categorization criteria in China and the geological section map of each station,and a set of empirical coefficients are suggested for the determination of maximum of design response spectra for sites of different categories upon calculating the EPA of different category sites and analyzing the results.
