Seismic, Hurricane, and Tsunami Vulnerability Database and Pinch-Point Taxonomy for Mid-rise Commercial Buildings

The database collects "vulnerability" data for multi-hazard performance-based early design of mid-rise commercial buildings. The data and metadata was obtained from the research literature and aligns with the Pacific Earthquake Engineering Research (PEER) Center’s framework for Performance-Based Earthquake Engineering (PBEE). In addition to earthquake response, fragility, and loss curves, applicable data from hurricane and tsunami research was collected and formatted in accordance with PEER-PBE conventions, i.e., as curves for conditional "pinch-point variables". A taxonomy of expanded multi-hazard pinch-point variables is provided, along with a description of soil-foundation-structure-envelope (SFSE) systems applicable to mid-rise commercial buildings. Database use and access is described in a README and is supported by a software utility for fragility curve parameter extraction. The database's representation of response curves obtained from Incremental Dynamic Analysis is also described. Use cases include: (1) Comparing different SFSE alternatives for mid-rise commercial buildings based on their earthquake, hurricane, and tsunami performance by structured queries and subsequent PBE assessment. (2) Developing a uniform schema for collecting alternate sources of fragility and vulnerability data to complement existing regional risk assessment tools. (3) Providing an introduction to PEER-PBE and its extension to multi-hazards. (4) Documentating other data and examples created by the Virginia Tech Resilient & Sustainable Buildings research team.
