## What is peer ground?

The Pacific Earthquake Engineering Research Center (PEER) ground motion database includes a very large set of ground motions recorded worldwide of shallow crustal earthquakes in active tectonic regimes.

## What is time history of earthquake?

The time history is the sequence of values of any time-varying quantity (such as a ground motion measurement) measured at a set of fixed times.

What are ground motion parameters?

Ground motion parameters were classified into four groups: Velocity, acceleration, displacement, and frequency.

### What is RJB in earthquake?

RJB. Joyner-Boore distance: closest distance to the horizontal projection of the. earthquake rupture plane (km)

1. Set the start time to something like 1950.
2. Enter the bounding box coordinates.
3. Get the CSV format in the output options.

What is time history and why is it important in the study of earthquake?

Time history analysis is a part of structural analysis and is the calculation of the response of a structure to any earthquake. It is one of the main processes of structural design in regions where earthquakes are prevalent.

## What is time history response?

Time-history is a plot of amplitude or acceleration vs time. In time history analyses the structural response is computed at a number of subsequent time instants. In other words, time histories of the structural response to a given input are obtained a result.

## What is spectral acceleration in earthquake?

PGA (peak acceleration) is what is experienced by a particle on the ground. SA (spectral acceleration) is approximately what is experienced by a building, as modeled by a particle on a massless vertical rod having the same natural period of vibration as the building.

What is meant by response spectrum?

A response spectrum is a plot of the peak or steady-state response (displacement, velocity or acceleration) of a series of oscillators of varying natural frequency, that are forced into motion by the same base vibration or shock.

### What is RRUP in earthquake?

RRUP. Rupture distance: closest distance to the earthquake rupture plane (km)

### What is Joyner boore distance?

1The Joyner-Boore distance is defined as the shortest distance from a site to the surface projection of the rupture plane.

What is RMS in earthquake?

In general, the smaller this number, the more reliable is the calculated depth of the earthquake. Rmss. The root-mean-square (RMS) travel time residual, in sec, using all weights. This parameter provides a measure of the fit of the observed arrival times to the predicted arrival times for this location.

## What is peer?

PEER graduated from NSF Funding in 2008 and is now supported by federal, state, local and regional agencies together with industry partners. Despite this funding shift, PEER continues to grow and remains an active earthquake engineering research center with a wide spectrum of technical activities and projects.

## What is the peer ground motion database?

The web-based Pacific Earthquake Engineering Research Center (PEER) ground motion database provides tools for searching, selecting and downloading ground motion data. ALL downloaded records are UNSCALED and as-recorded (UNROTATED).

What is the peer reports series?

The PEER Reports Series comprises state-of-the-art research in earthquake engineering and related fields by the more than 150 expert members of the PEER universities consortium. The current emphasis of the series is on performance-based engineering of lifelines and building structures.

### Who is behind the peer Center report?

This report was prepared by PEER staff, led by Khalid Mosalam, Amarnath Kasalanati and Grace Kang. It contains a summary of research, educational and outreach activities at the PEER Center since January 2016. Graphic Handout: – Fire Following Earthquake: Will water be there for firefighters?
