Abstract

Shaking Table Tests of Columns

Shaking Table Tests of Columns was compiled by Yaqiong Li and Dr. Kenneth J. Elwood from the University of Auckland . It includes 86 dynamic tests of reinforced concrete frames from 7 test sets.

The database contains reports, parameters, and files including data, media, drawing and diagrams from tests. The parameter set includes five categories:

  • Column Information
  • Material Property
  • Specimen Geometry
  • Reinforcement Layout
  • Experimental Results

Each row in this dataset contains the following information: 

  1. Title: Test Name (assigned by the compiler)- Title of the project, group of experiments, simulations or surveys (assigned by the source(s))
  2. Experiment or Case ID: Column ID (assigned by the compiler)- Test Series
  3. Keywords: Words describing the dataset
  4. Report(s): Related documentation
  5. Parameters: Variables and parameters chosen by the researcher, compiler, professional or scientific organization to describe the data
  6. Data: Data files generated through project.
  7. Photos, Videos, etc.: Media files including photos, videos, audio generated through project
  8. Drawings/Diagrams: Drawing and diagrams helpful to interpret the data
  9. Source: Names of the people who generated the data
  10. Compiled by: Names of the people who compiled the data
  11. Compiled on: Date when the dataset was compiled

Parameter definitions and notations used in the database are as follows and are also available under supporting documentation:
