The effects of the 17 August and  12 November 1999 Earthquakes in Turkey were investigated by a team of students and faculty from many universities. The damage caused to reinforced concrete structures was documented. More information about the reconnaissance effort can be found here : 2016/02/00396/Donmez_and_Pujol_2005.pdf

This database consists of coordinates, extent of damage and photographs (if available) of  1127 low-rise reinforced concrete buildings from the towns of Bolu and Duzce. 

The above image shows the location and damage level of buildings in Bolu. Damage level is depicted as follows: Severe Damage (Removed) = Red Diamonds, Severe Damage= Red, Moderate Damage= Orange, Light Damage= Yellow and No Damage= Green.

The above image shows the location and damage level of buildings in Duzce. Damage level is depicted as follows: Severe Damage (Removed) = Red Diamonds, Severe Damage= Red, Moderate Damage= Orange, Light Damage= Yellow and No Damage= Green.

The Google Earth (.kml) file for the map shown can be downloaded under the supporting documents tab.

This database is presented as a spreadsheet with each row containing the following information for 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
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 diagrams helpful to interpret the data
10. Data: Data files generated through project. Tabular text format is preferred
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

The following information is presented in the parameters column: 

    1. Latitude

    2. Longitude

    3. No. of Floors

    4. Structural 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 least one floor slab or part of it lost its elevation
