Model Description

Model Form

$$l =\left( {{\eta _S} \cdot {C_S} + {\eta _{ND}} \cdot {C_{ND}} + {\eta _{NA}} \cdot {C_{NA}} + {\eta _C} \cdot {C_C}} \right) \cdot A \cdot \exp \left( { - r \cdot t} \right) \cdot \varepsilon $$ where Building repair cost model gets the “\({A}\)” parameter from the Building information model.
Important Notes:
• if the structural damage ratio exceeds the threshold, i.e. \({\eta _S}\) > \({\eta_R}\), all damage ratios are set to 1 and the loss is computed based on the modified values
• The cost of repair operation is computed once it is completed (i.e. the repair status changes to 1), otherwise it is 0.
• To use this model in analyzers other than Discrete Event Sampling Anlyzer, the "RepairStatus" property must be a constant parameter with current value of 1
• For further information on this model, refer to Mahsuli, M., Haukaas, T. (2013) and Mahsuli, M., Haukaas, T. (2013).

DDM sensitivities

• No

Properties

Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

Building Information Model

• A building information model object that returns the total area of the building, \({A}\), to this model.

Repairability Structural Damage Ratio

• \({\eta_R}\) = The threshold of Structural Damage Ratio by which the building can be repaired, otherwise, it needs to be demolished and reconstructed

Structural Damage Ratio

• \({\eta_S}\) = Structural damage ratio

Nonstructural Drift Damage Ratio

• \({\eta_{ND}}\) = Non-structural drift damage ratio

Nonstructural Acceleration Damage Ratio

• \({\eta_{NA}}\) = Non-structural acceleration damage ratio

Content Damage Ratio

• \({\eta_C}\) = Content damage ratio

Structural Unit Area Cost

• \({C_S}\) = Structural unit area cost (given as a real number)

Nonstructural Drift Unit Area Cost

• \({C_{ND}}\) = Non-structural drift unit area cost (given as a real number)

Nonstructural Acceleration Unit Area Cost

• \({C_{NA}}\) = Non-structural acceleration unit area cost (given as a real number)

Content Unit Area Cost

• \({C_C}\) = Content unit area cost (given as a real number)

Time

• \({t}\) = Time object

Annual Interest Rate

• \({r}\) = Annual interest rate

Epsilon

• \({\varepsilon}\) = Model error

Repair Status

• \({\varsigma}\) = Status of Repair operation (1 if completed, 0 otherwise)

Output

• \({l}\) = Loss due to the repair cost
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
