This database contains building information of 616 low-rise reinforced concrete buildings with earthquake damage collected during seismic vulnerability assessment from 6 different earthquakes (Erzincan 1992, Duzce 1999, Bingol 2003, Peru 2007, Wenchuan 2008, and Haiti 2010). With a goal to evaluate the Priority Index proposed by Hassan and Sozen (1997), the reconnaissance team from 6 different earthquakes collected a total number of 7,044 photographs of 616 structures which were constructed with reinforced concrete or concrete masonry units.

This database is presented as a spreadsheet with each row containing the following information of a building:

1. Title: Title of the project, group of experiments, simulations or surveys
2. Source: Names of the people who generated the data
3. Keywords: Words describing the dataset, which can be used for searching
4. Report(s): Related documentation
5. Experiment or Case ID: ID assigned by the source to the sample, specimen, case, survey, site, experiment or simulation
6. Latitude: Latitude of the location where data was collected, if applicable
7. Longitude: Longitude of the location where data was collected, if applicable
8. Parameters: Variables and parameters chosen by the researcher, compiler, professional or scientific organization to describe the data
9. Drawings/Diagrams: Drawing and diagram files needed to interpret the data
10. Data: Data files generated through project. Tabular text format is preferred (e.g., *.txt, *.csv).
    It is recommended that data files are organized in columns with each column having a descriptive header (e.g., sensor ID and unit)
11. Photos, Videos, etc.: Media files including photos, videos, audio generated through project
12. Compiled by: Names of the people who compiled the data
13. Date: Date when the dataset was compiled. (format: yyyy-mm-dd)

In addition, the following are the information presented in the parameter column:

1. Event
2. Building ID
3. Priority Index (Hassan Index, %): PI = WI + CI (where, WI = Wall Index, CI = Column Index)
4. No. of Floors
5. 1st Floor Area (m^2)
6. Total Floor Area (m^2)
7. Column Area (m^2)
8. Concrete Wall Area (NS) (m^2):
   Data from Wenchuan collected as y-direction are assumed to be North-South direction
9. Concrete Wall Area (EW) (m^2):
   Data from Wenchuan collected as x-direction are assumed to be East-West direction
10. Masonry Wall Area (NS) (m^2):
    Data from Wenchuan collected as y-direction are assumed to be North-South direction
11. Masonry Wall Area (EW) (m^2):
    Data from Wenchuan collected as x-direction are assumed to be East-West direction
12. Structural Damage - Four classes of Damage
    a) Light: Hairline (crack width not exceeding approximate 0.13 mm) inclined and flexural cracks were observed in structural elements
    b) Moderate: Wider cracks or spalling of concrete were observed.
    c) Severe: At least one element had a structural failure.
    d) Collapse: At lease one floor slab or part of it lost its elevation
13. Masonry Wall Damage - Damage to infill walls classified as follows:
    a) Light: Hairline cracks occurred.
    b) Moderate: Wider cracks appeared or large pieces of plaster flaked off.
    c) Severe: The element collapsed or cracks wide enough to see through the wall appeared.
14. Captive Columns: Are there captive columns?
15. Column Index (%)
    CI = 0.5 Acol/Af *100%
    where,
    Acol: the sum of cross-sectional areas of all columns at ground floor.
    Af: total areas above ground levels
16. Wall Index (NS) (%)
    WI = (Acw + 0.1Amw)/Af *100%
    where,
    Acw: the sums of cross-sectional areas of reinforced concrete walls in north-south direction at ground floor
    Amw: the sums of cross-sectional areas of infill masonry walls in north-south direction at ground floor
17. Wall Index (EW) (%)
    WI = (Acw + 0.1Amw)/Af *100%
    where,
    Acw: the sums of cross-sectional areas of reinforced concrete walls in east-west direction at ground floor
    Amw: the sums of cross-sectional areas of infill masonry walls in east-west direction at ground floor
18. Min WI (%)
    Minimum Wall Index
19. Priority Index (Hassan Index, %)
    PI = WI + CI
    where, WI = Wall Index, CI = Column Index
