This is the web repository of the Risk Modeller's Toolkit (RMTK). The RMTK is a suite of tools developed by scientists working at the Global Earthquake Model (GEM) Foundation. The main purpouse of the RMTK is to provide a suite of tools for the creation of seismic risk input models and for the post-processing and visualisation of OpenQuake risk results.

###Plotting Tools

The toolkit contains the following functionalities for visualising seismic risk results (please refer to the documentation and tutorial for more information):

• OpenQuake Hazard Results

  • Seismic Hazard Curves
  • Seismic Hazard Maps
  • Uniform Hazard Spectra
  • Ground Motion Fields

• OpenQuake Risk Results

  • Loss Exceedance Curves
  • Loss Maps
  • Collapse Maps
  • Damage Distribution Statistics

###Risk Tools

The toolkit contains the following functionalities for post-processing probabilistic seismic hazard and risk results (please refer to the documentation and tutorial for more information):

• Probable Maximum Loss Calculator
• Logic-Tree Branch Selector

###Vulnerability Tools

The toolkit contains the following functionalities for constructing seismic risk input models (please refer to the documentation and tutorial for more information):

• Capacity Curve Modelling Methods:

  • ''DBELA'' method
  • ''SP-BELA'' method
  • Point Dispersion method

• MDOF → Equivalent SDOF Conversion Methods:

  • First mode approximation (Eurocode 8, 2004)
  • Adaptive approach (Casarotti and Pinho, 2007)

• Direct Nonlinear Static Methods:

  • ''R–μ–T'' relation (Dolšek and Fajfar, 2004)
  • ''SPO2IDA'' (Vamvatsikos and Cornell, 2006)
