From research to practice.

Empowering global resilience with user-friendly tools for catastrophe risk modelling and engineering analysis, so that complex problems are tackled with the right know-how.

Each application runs on the Djura platform and ships as an installable part of the djura Python package.

• 

  Record selection

  Ground motion record selection based on the generalised conditional intensity measure (GCIM) approach and code-based criteria.

  djura[record_selection]
• 

  Hazard consistency

  Checks that selected ground motions are consistent with the site hazard across intensity measures.

  djura[hazard_consistency]
• 

  EDP-IM models

  Machine-learning models relating seismic intensity measures to structural response.

  djura[edp_im]
• 

  IM conversion

  Converts fragility and vulnerability models between intensity measures for regional risk analysis.

  djura[im_conversion]
• 

  Vulnerability modeller

  Seismic vulnerability and loss modelling, including machine-learning models.

  djura[vulnerability_modeller]
• 

  Storey loss functions

  Generates storey loss functions linking engineering demand parameters to monetary losses in structural and non-structural elements.

  djura[slf]

djura

A scientific Python toolkit bundling the core algorithms behind the platform: record selection, hazard consistency, EDP-IM prediction, IM conversion, vulnerability modelling and storey loss functions. Free for research and education under AGPL-3.0; commercial licences are available from Djura.
