【摘要】：系统介绍了国内外各类抗震设计规范和导则中关于设计地震动时程方面的规定。分别从时程分析范围、时程组数以及天然时程所占比例、设计地震动时程的峰值和反应谱特性、设计地震动时程的持时特性以及设计地震动时程的相关性等5个方面,对比了不同行业抗震设计规范中关于地震动时程相关规定的异同。以我国现行《建筑抗震设计规范》为例,给出了满足相关要求的设计地震动时程,并针对设计地震动时程确定过程中需要关注的问题进行了讨论,以期为我国地震安全性评价工作中设计反应的确定谱提供参考。
[Abstract]:This paper systematically introduces the provisions of various seismic design codes and guidelines at home and abroad concerning the design time history of ground motion, respectively from the scope of time history analysis, the number of time history groups and the proportion of natural time history. There are five aspects: the peak value and the response spectrum of the design time history of the ground motion, the duration characteristic of the design time history of the ground motion and the correlation of the design time history of the ground motion. In this paper, the similarities and differences of the time history of earthquake ground motion in different codes for seismic design of different industries are compared. Taking the current Code for Seismic Design of buildings in China as an example, the design time history of ground motion that meets the relevant requirements is given. In order to provide a reference for the determination of design response in the seismic safety evaluation work in China, the problems that need to be paid attention to in the process of determining the time history of the design ground motion are discussed in this paper.
