General Introduction:

The dataset "DatabasePublic.mat" contain the information retrieved from 386 damage surveys (in the form of .pdf hardcopies)
performed in the Netherlands by different third parties, and collected by the Authors. Such information was digitalized with a systematic
procedure involving reading the information from the hardcopies and from the technical drawings, and typing it into the .mat file.
Whenever the technical drawings were not in scale, but with an indication of it (e.g. 1:500), the values of distances and displacements 
were read after rescaling the technical drawings in AutoCAD.

These data are made public both for the publications and the PhD thesis of Alfonso Prosperi, and for other researchers to use these data
in their own work. Due to the nature of this study, the dataset does not include the addresses, or pictures of the surveyed buildings, 
to ensure the privacy of the residents and/or owners.

For the same reason, the original hardcopies are not publically available.

Description of the available information in the .mat file:

ID: name of the case:

  "B" stands for "building" while the numeration has no particular meaning and it is intended just to differentiate the cases.

Province: the province in which the building is located.

City: the city in which the building is located.

Construction_year: year of construction.

Type: to four typologies proposed in Exposure Database v5 by NAM, based on the structural features and the adjacency with other structures:

  Unit House (UH), refers to freestanding houses, (e.g. a single detached house) with an independent foundation system.
  Block Unit Single (UBHS), refers to a single building part of an homogeneous block (e.g. a single address of a block of row houses, or a semi-detached house).
  Block Unit Multiple (UBHM), refers to an homogeneous building block, with the same foundation system (e.g. a block of row houses).
  Others (OTH), refers to cases not classified in the previous 3 categories (e.g. sheds or warehouses).

Foundation: foundation categoy:

  S stands for Shallow;
  D stands for Deep (i.e. piled);

Wall: structure field cointaining the settlement profiles per wall, 2-coordinate (x,z) with a vector for each coordinate. 
      This values can be plotted to visualize the recorded settlement profile under the building. "x" is the abscissa along the wall 
      lenght (in meters)."z" is the recorded vertical displacement (in millimiters).

Measurements_type: type of measurements in the field "Wall".

  'Differences from a reference 0 point': the relative 0 of the measurements refers to a point of a bed joint. 
  'Height of the points from the ground level': the relative 0 of the measurements refers to a point not from the bed joints 
                                                (supposevely the ground level). Measurements of this type can present high values of "z". 

Damage: building damage class according to the damage severity.

  No damage;
  Light Damage;
  Moderate to Severe;
