设计地震力 meaning in English
design seismic force
Examples
- After considering the influences of the tensility performance and ratio of damping on the earthquake action of steel structure , the reference formula to design the earthquake force based on the is given
在考虑了钢结构的延性性能、阻尼比等因素对结构地震作用的影响之后，给出了采用概率延性调整系数的设计地震力的参考公式。 - So , we can draw some conclusions as follows : the method of upgrading the seismic - measures which is adopted by gb50223 - 95 is effective and is more effective than the method of upgrading the earthquake - design - level for those category frames of which seismic - measures are needed to be upgraded from grade 2 to grade 1 . but for those category frames of which seismic - measures are not upgraded from grade 2 to grade 1 ( e . g . those frame of which seismic - measures are needed to be upgraded from grade 3 to grade 2 or from grade 4 to grade 3 ) , whether the method of upgrading seismic - measure is more effective than the method of upgrading earthquake - design - level needs further research
因而可以有如下结论， gb50223 - 95对乙类建筑所采用的提高抗震措施等级的设计思路是有效的，并且，对于抗震措施需从二级提高到一级的乙类建筑，该方法比提高设计地震力的方法更为有效；但对于抗震措施不是从二级提高到一级（如从三级提高到二级、或从四级提高到三级）的乙类建筑，提高抗震措施等级的方法是否一定比提高设计地震力的方法更有效尚需作进一步探讨。 - The three frames are category frame without upgrading seismic - measures and earthquake - design - level , category frame of higher seismic - measures and category frame of higher earthquake - design - level . then , the author carries out nonlinear dynamic analysis on three frames under intermediate earthquake action and rare earthquake action . the results show as follows : ( a ) the performance of the two category frames of higher seismic - measures or higher earthquake - design - level are much better than that of category frame ; ( b ) the earthquake - design - level of higher earthquake - design - level category frame is upgraded by 50 percent , which is a high limit that is adopted by foreign codes
结果表明：按照提高抗震措施等级设计的乙类建筑框架和按照提高地震力设计的乙类建筑框架在地震作用下的反应都明显好于仅按丙类建筑进行抗震设防的框架；提高设计地震力的乙类建筑框架的设计地震力提高幅度为50 % ，与国外重要建筑地震力提高幅度相比已经是一个上限水准，但分析结果仍然显示，这样设计出来的乙类建筑框架，无论是在中震还是在大震作用下，其表现出来的抗震性能都不及提高抗震措施等级的乙类建筑框架。 - Chinese seismic design code has adopted the popular seismic design concept in the world , that is , using reasonable combination of " seismic design force - ductility grade " and the concept of " capacity design " to set up an ideal energy - dissipation mechanism behaving inelastic dynamic response characters to resist given seismic intensity
中国建筑抗震设计规范采纳了当今世界各国主流的抗震设计思想，即以合理的“设计地震力- -延性等级”的组合和“能力设计( capacitydesign ) ”的思路来构架具有合理的非线性地震响应特征的耗能机构抵御预定水准的地震作用。 - National standard ? 《 standard for classification of seismic protection of buildings 》 ( gb50223 - 95 ) adopts the method of upgrading the seismic - measures to upgrade category structure ' s earthquake - resistance level . it is different from some foreign codes ( such as us 、 new zealand ) which adopt the method of upgrading the earthquake - design - level . the main topic of this dissertation is to study which method is more effective
国家标准《建筑抗震设防分类标准》 （ gb50223 - 95 ）中对乙类建筑采用的是通过提高抗震措施等级来提高其设防水准的方法，这与国外（如美国、新西兰、欧共体等）对重要建筑所采用的提高设计地震力的方法有概念上的差异。
