A toolkit of extensions for using o3seespy for geotechnical simulations

o3soil is high-level package that takes advantage of several libraries to perform geotechnical analyses without rewriting common functions.

The package is based on the generic sfsimodels package soil object (sfsimodels.Soil()), soil profile object (sfsimodels.SoilProfile()) and building object (sfsimodels.Building()), as well as the the acceleration time series object from the eqsig package (eqsig.AccSignal()). These objects allow soil, building and ground shaking to be defined in an agnostic way which is compatible with other software and Python packages and export them to json file format. The toolkits in this package convert the generic objects into o3seespy objects and run an OpenSees analysis.

The eco-system of Python packages that relate to this package are outlined in the figure below.

• Site response analysis
• Seismic Soil-foundation-structure interaction
• Foundation bearing capacity
• Liquefaction triggering
• Element test behaviour
• Lateral spreading
