2.3. Response Data File

The response data file provides the demand data for the assessment. Demands are either Engineering Demand Parameters from a response simulation or Intensity Measures from a hazard assessment. The types of demands provided must match the types of demands requested by the fragility functions.

The data is expected in CSV file format. The first line of the file is a header that identifies the types of EDPs in the file. pelicun uses SimCenter’s naming convention for EDPs (see Fig. 2.3.1). There are four pieces of information provided in the name of each EDP:

event_id

Identifies the event in a multi-event scenario. 1 is used for single-event studies.

EDP_type

Specifies the type of EDP provided. pelicun currently supports the following EDP types in response data files:

PID

Peak Interstory Drift Ratio

RID

Residual Interstory Drift Ratio

PRD

Peak Roof Drift Ratio

PFA

Peak Floor Acceleration

PFV

Peak Floor Velocity

PGA

Peak Ground Acceleration

PGV

Peak Ground Velocity

PGD

Permanent Ground Deformation

location

Specifies the location where the EDP was measured. In buildings, locations typically correspond to floors with 0 being the ground for accelerations and 1 being the first floor for drift ratios.

direction

Specifies the direction of the EDP. In buildings, typically the two horizontal directions are used and they are labeled as 1 and 2. Any numbering logic can be used here, but the labels must match the ones provided under Components in the Configuration File (see Section 2.2)

Each row in the file provides EDPs from one simulation. EDP units are assumed to follow the unit specification in the Configuration File.
