Risk assessment using fragility and consequence model

[XUEJIAO LONG]

Hi Everyone,

I am trying to construct my risk analysis model to get seismic loss for the region of a given return period. And referring to this discussion, since I have a set of fragility and consequence model, I can directly use it instead of a vulnerability model.  https://groups.google.com/g/openquake-users/c/cY56plkNBoM/m/gzVDc_ukAQAJ

So I tried to construct my configuration file. I separated my hazard and risk part. The hazard analysis went well, but when I run the risk part under calculation_mode = classical_damage, it is working but produce a scenario result. So I tried to run it under calculation_mode = classical_risk, It produces the following error. 

AttributeError: 'ArrayWrapper' object has no attribute 'mean_loss_ratios_with_steps'

The configuration file is attached in case it is a syntax error.

In the manual, there is little information on this part. I was wondering if there are more details on how to run the classical risk analysis using fragility and consequence model.

Thank you,

Xuejiao Long

Hi Xuejiao,

The combination of fragility and consequence model files as inputs is supported for scenario_damage and event_based_damage, but unfortunately, it is not yet supported for classical_damage calculations. You should be able to use the event_based_damage calculator to obtain your required risk outputs.

Best regards,
