The SP3 RiskModel is tailored for preliminary resilient design, advanced due-diligence assessments, and insurance risk applications. You can produce a building and site specific risk assessment without an expensive engineering evaluation. With minimal information or using an extensive set of optional inputs create a more accurate risk assessment than any other available method.
Provides automated soil and VS30 look-up.
Provides automated soil-specific hazard information.
This provides site-specific design information based on lat/long and building age, including digitized design maps, covering current design back to the 1927 Uniform Building Code. This database includes both seismic and wind design and is used to determine building design strength, design stiffness, and design information for non- structural components.
This Engine creates an archetype structural model for the building, leveraging many other source SP3 databases. This includes modal information based on building type and design information, accounts for the strength and stiffness contribution of the gravity system and non-structural components, and accounts for other sources of design overstrength.
This Engine computes the nonlinear structural responses of the building (nonlinear drifts, floor accelerations, etc.), in a manner that is specific to the design and dynamic properties of the building. This Engine uses the SP3 Structural Responses Database which includes millions of structural response results from nonlinear dynamic time-history analyses.
This Engine populates the structural and non-structural components into the damage model, in a manner that is consistent with the building occupancy, structural design or retrofit data, non-structural design or retrofit date, and building code design requirements for the specific site location for the date of construction.
The fragilities database includes detailed information on damageability, repair costs, and repair times for nearly one thousand building components. This includes the 796 fragility components from the publically-available FEMA P-58 database, supplemented by the 174 additional fragilities created by the SP3 team with input from SP3 users.
This Engine then runs the detailed statistical analysis incorporating all of the information from the previous Engines and Databases. This results in detailed building-specific vulnerability curves, for repair costs and repair time, which quantify both the average values and the uncertainties in the risk.
The scope of the SP3 RiskModel is broad and covers all common types of buildings in the United States. Available building types and applicable height ranges are listed in the following table.
