1 . the research actuality of site classification methods at home and abroad was outlined , the related regulations on site classification in all kinds of seismic design codes were briefly summarized 简要总结了场地分类的研究现状和国内外抗震设计规范中关于场地分类的方法,对我国历代建筑抗震设计规范中关于场地分类的有关内容进行详细总结,并对其演变加以分析和评述。
To the structural characteristics , earthquake characteristics of the masonry building with frame - shear wall at first floor , combined with " the antidetonation design specification of the building " , this paper has proposed some main design points from four respects 摘要针对底部框架抗震墙砖房的结构特点、震害特点,结合《建筑抗震设计规范》 ,提出了四个方面的设计要点。
In fact , there should be different design spectra corresponding with the structures of different damping - ratios , the new code for seismic design for buildings ( gb50011 - 2001 ) has provided corresponding spectra for structures with different damping - ratios 事实上,具有不同阻尼比的结构就应有不同设计反应谱与之对应, 《建筑抗震设计规范》 ( gb50011 - 2001 ) [ 6 ]已规定了不同阻尼比的标准设计反应谱。
It is shown that the lateral stiffness ratio of the third story to the second story suggested by the latest 《 code for seismic desing of building 》 ( gb50011 ) is relatively low and the reasonable value is proposed , which can be used for referrence to engineering designers 根据计算结果的分析,认为新颁布的《建筑抗震设计规范》 ( gb50011 )对于砌体过渡层与第二层框剪层的侧向刚度比限值偏小,并提出了合宜的刚度比取值范围,可供设计人员在抗震设计时参考和借鉴。
A primary scheme of site classification was presented , in this scheme a new site classification method that can consider the profiles containing bottom , mid or top soft layer was put forward on the basis of the site classification in the current code for seismic design of buildings 提出了基于土层结构的场地分类的初步方案。在现行建筑抗震设计规范四类场地划分的基础上,进一步根据不同土层结构对每类场地再细划分为三个亚类,并给出其相应的设计反应谱。
