Ground motion selection and Scaling using PEER NGA Database

Selection and scaling of Ground motion from PEER NGA Database for Response history analysis. This needs a target spectra for scaling the ground motions. Target spectra may be UHS, CMS, Code specifed target spectra or GMPEs.

Thanks, Bhaiya.
Can you please upload more useful videos like this.

Sure. :-)

Sir, How did you plot spectra in Excel ?Can you please share

Sir, does the RSN1 means the acceleration in the first row?..pls reply

[@ravikanth5936]

PEER contains 20k+ ground motions. RSN means record sequence number which is assigned to each record.

How to scale the time acceleration data like 0.1g, 0.2g..

[@ravikanth5936]

There are many proposed ground motion scaling schemes. The most basic one is amplitude scaling. You can scale your ground motion by a factor to get the desired PGA.

There are 5 data in a row of acceleration time history how could we plot this on excel file

[@ravikanth5936]

It might be difficult to put it in a column in excel. You can use matlab for the same. A small command can work.
