[Tool] PEER NGA Ground Motion Convertor [PEER地震波数据格式转换器]

太平洋地震工程研究中心(PEER)强震数据库格式转换器。程序可以将原本5列的地震波数据转换成任意列,并支持地震波峰值的调整、地震波时间间距的调整,方便工程和研究。程序支持转换旧数据库(NGA-West)和新数据库(NGA-West2)的地震波文件。NGA-West2 网址: http://ngawest2.berkeley.edu/。A program can be used to transform a PEER Ground Motion Database file into a user-specified format suitable for other applications to use.The program can transform the data format from 5-column to any column. The peek value and time step of the ground motion can also be adjusted . It’s easy to use.The program supports both the NGA-West and NGA-West2 Database file . The address of NGA-West2 Database : http://ngawest2.berkeley.edu/ .
