结构分析用地震波

Sui_Ji_Di_Zhen_Bo_Sheng_Cheng_Ruan_Jian

在时程分析时需要使用地震波,一般真是地震波更具有说服力,上次电脑重装之后发现地震波没了,就去重新下载一下,结果发现不能下载了,着实把我吓了一跳,虽然有很多的地震波,但是数得上名字而且又能用的却没有几个,国内的地震波大多数是需要付费的,所以还是从国外找,这里备份一组地震波,以便于下次自己使用,地震波摘自berkeley网站,分别是50年超越概率为10%、2%和50%的,一共六十条。

下面提供Los Angeles地震的地震波详细数据,数据来自于实际记录,并调幅以使得其反应谱符合1997 NEHRP的设计谱。

These acceleration time histories have been derived from historical recordings or from physical simulations and have been altered so that their mean response spectrum matches the 1997 NEHRP design spectrum, modified from soil type of SB-SC to soil type SD and having a hazard specified by the 1997 USGS maps.

There are 20 different horizontal components (10 2-component records). Each original historical ground motion pair has typically been altered in the following way:

  • The two horizontal components originally provided were resolved into fault-normal and fault-parallel orientations.
  • The records are adjusted in the frequency domain to have characteristics appropriate for NEHRP SO soil sites.
  • The records are amplitude scaled so that the average of the two horizontal spectra match the target spectrum.
  • The individual components were rotated 45 degrees away from the fault-normal fault-parallel orientations

    你好,我想请教你关于弹塑性时程分析选波的问题。时程分析时,将时程曲线进行谱分析,与设计反应谱对比,是拿的多遇地震的地震影响系数还是罕遇地震的地震影响系数进行分析吗?

    • 伊犁的秋天   •     Author

      目前两阶段设计中,弹塑性分析设计只针对于罕遇地震的验算评估,多遇地震规范未规定需要进行弹塑性分析,所以应该是和罕遇地震的相比较。

      • jingwen56   •  

        比如8度二类场地,用多遇地震的地震影响系数曲线进行选波,然后将加速度峰值调为罕遇地震下的值,这样选波可以吗

        • 伊犁的秋天   •     Author

          一般来说注意场地类别的话就差不多可以了,但是如果要更加准确的话,为什么不适用相应的软件直接将罕遇地震的谱随机生成相应的地震波。
