HazardCurve
Reads the hazard curve file and creates ground motion bins for time-based assessment.
Description
The HazardCurve UserObject is a part of the Seismic Probabilistic Risk Assessment framework in MASTODON. The HazardCurve UserObject reads the hazard curve data from a .csv file and divides the hazard curve into a number of bins provided by the number_of_bins parameter. Currently, the UserObject assumes that the hazard curve is provided as the Mean Annual Frequency of Exceedance (MAFE) of the peak ground acceleration (PGA). The hazard curve is binned by linearly interpolating the hazard curve in a log-linear scale (MAFE in the log scale and PGA in the linear scale). Each bin is assigned a PGA value that is the midpoint of the bin. After binning the hazard curve, the HazardCurve UserObject also scales the ground motions read by the GroundMotionReader for use in risk assessment for each hazard bin. For this purpose, it is assumed that the input ground motions are at a reference PGA provided by the reference_acceleration input parameter. The ground motions are then linearly scaled to the PGA of each bin and then used for risk assessment.
The listing below provides a sample application of the HazardCurve and GroundMotionReader UserObjects. In this application, the ground motions with a specific pattern are read and a hazard curve is read from the file hazard.csv. This hazard curve is split into two bins and the ground motions (assumed to be provided at a reference PGA of 0.4g) are scaled to these bins.

Default:10
C++ Type:unsigned int
Controllable:No
Description:The number of bins to create from the hazard curve data.
Optional Parameters
- allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
Default:False
C++ Type:bool
Controllable:No
Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
- execution_order_group0Execution order groups are executed in increasing order (e.g., the lowest number is executed first). Note that negative group numbers may be used to execute groups before the default (0) group. Please refer to the user object documentation for ordering of user object execution within a group.
Default:0
C++ Type:int
Controllable:No
Description:Execution order groups are executed in increasing order (e.g., the lowest number is executed first).
