Intro
This plugin generates response spectrum and artificial earthquakes for time history analysis according to standards and creates graphs.
Using the design spectrum, artificial seismic waves can be generated and converted into spectrum load graphs.
It includes the ASCE7 spectrum series standard and data is obtained from the USGS Seismic Design Geodatabase.
Version
- v1.0.0 : Plugin release
Applicable Standards
- American Standard (ASCE7-22)
Benefits of this plugin
The plugin provides Response Spectrum data based on the ASCE7-22 standard, drawing from the USGS Seismic Design Geodatabase. It fetches latitude and longitude data for specified regions and offers four types of RS Data:
- Two-Period Design Spectrum
- Two-Period MCEr Spectrum
- Multi-Period Design Spectrum
- Multi-Period MCEr Spectrum
Additionally, based on the generated RS Data, it creates matched artificial ground motion data through RS matching (Spectral matching) to align with the target spectrum.
- Generates accurate response spectra and artificial seismograms according to standards.
- Provides reliable results using USGS data.
- Visualizes the generated data in graphs for easy analysis.
- Features an easy-to-use interface for selecting design criteria and entering data.
How to use this plugin?
Spectrum Standard Selection
1. Launch the plugin and select the design spectrum standard (ASCE7-22)
Target Address Entry
2. Enter the target address and click the Search button. Enter the address directly (by Address) or by latitude/longitude coordinates(by Latitude/Longitude).
Seismic Data Input
3. Set the Risk Category ,Soil site Class and Design Spectrum Option.
Design Spectrum Calc.Button
4.Click the Calc.Design Spectrum button to calculate the response spectrum.
Set Artificial Earthquake Data
5. Enter values appropriate for the earthquake scale considering Rise,Level,Total time and Damping Ratio for calculating artifical earthquake data.
Artificial Earthquake Calc.Button
6.Click the Calc.Artificail Eqrthquake button to generate the time history function data.
Analyze the Resulsts
7. Visualize the result graphs for analysis
Data Update
8. Click the Update RS Function or Update TimeHistory Function button to import the result data into the program.
Note
How to generate response spectrum data
To generate RS data, first search the target area and enter the seismic risk factor and seismic zone efficient in the Seismic Data. Then, click the Calc. Design Spectrum button, and the plugin output the Response Spectrum data based on the USGS Seismic Design Geodatabase. Also, after reviewing the visualized and textual results, click the Update RS Function button to import the data into Civil NX (RS Functions).
How to generate artificial earthquake for time history analysis
To generate TH data, select design criteria in the design spectrum and enter input data for the function such as Envelope Function data / Maximum Acceleration / Damping Ratio and so on input the values that correspond to the seismic intensity being evaluated.
Then, click the Calc. Artificial Earthquake button, and the plugin generate artificial earthquakes and convert them into spectral or acceleration graphs. Also, after reviewing the visualized and textual results, click the Update TimeHistory Functions button to import the data into Civil NX(TimeHistory Functions).
The generated artificial seismic waves can be converted into spectrum and acceleration graph types by Graph Type.
Conclusion
This guide enables you to effectively generate and analyze response spectra and artificial seismograms for time history analysis using the new standard (ASCE7-22) RS and Artificial Seismogram Generator plugin.
