This page is intended to help users get their own building fragilities into Ergo. 


File Types and Format

There are two acceptable formats, comma separated value (CSV) and Extensible Markup Language (XML). The simplest way to get fragilities into Ergo is the CSV format which will internally be converted to XML. Both formats will be explained in their own section after the field descriptions.

Field Descriptions

Field NameField DescriptionField TypeAcceptable ValuesInformational
IDUnique numeric identifier in the fragility datasetInteger No
Fragility ID CodeUnique key for each fragility (e.g. SF_C1_1 for structural fragility for C1 structure type)String No
AuthorIdentifies the person(s) who provided each fragility set.String Yes
Structure TypeStructure Type this fragility curve is designed forString Yes
StoriesIdentifies the number of stories used for the model building when constructing fragilities. .IntegerA value of “0” indicates multiple story levels were considered (for fragility surfaces)Yes
DescriptionA textual description providing information about the derivation of this fragility curve setString Yes
Ground MotionsGround motion records used for time-history analyses when constructing fragilitiesString Yes
CodeDesign code for the fragility setString Yes
Damage TypeThe type of damage type this fragility representsString Yes
Demand TypeThe demand type required by the fragility, can include the period if applicable (e.g. 0.2 Sa )String No
Demand UnitThe units of the demand typeString No
Limit StatesThe limit states which define the transitions between damage states for each fragility set.String No
T Eqn TypeEquation to estimate the natural period of a building.Integer No
Frag Eqn TypeFragility equation type.Double No
ParametersThe number of fragility parameters (e.g. 6 if three curves with median and beta), 18 if a surface.Integer 



Import Sample Fragility

You can download an example CSV file with fragility data here: Ergo_Fragility_Example.csv  After downloading the sample building fragility file, follow the steps found in the Bridge Fragility example to ingest the data. The only difference will be when selecting the data type, select Building Fragilities. The rest of the steps are identical.
