| 摘 要： | 长周期地震波的研究对自振周期较长的大型结构的抗震设计具有重要意义。目前国内外主要的长周期地震波分析方法大致可分为两类:经验统计方法和地震学中的震源模型方法,通过对这两类方法的研究现状和适用范围的分析,提出了在地震动长周期的研究和应用中有待解决的关键问题。为了将长周期分析方法应用于大跨结构的抗震设计,还介绍了我国现有的抗震设计规范谱中对长周期部分的修正方法。 |

| Abstract: | The study of long-period seismic wave is significant to the seismic design of the large-span engineering structures with long auto-oscillation period.At present,there are two kinds of major long-period seismic wave analysis methods in the world:statistical methods and seismological methods.The present research status and applicable range of every kind of methods are introduced,and the key problems that need to be solved in the research and application of long-period seismic wave of ground motion are put forward.For the use of response spectrum method to the seismic design of large-span structure,the revises are expounded about the design response spectra in the long period part in current Chinese architectural seismic design codes. |
| Keywords: | long-period seismic wave ground motion source model response spectrum attenuation law research develop architectural anti-seismic design code |
