Exposure and fragility of a virtual oil refinery testbed for seismic risk assessment

Description

Table of contents (English)

In the repository, the database related to the refinery assets examined is structured in folders per structural type, namely Liquid Storage Tanks, Buildings, Pressure Vessels, and High-Rise Stacks. In each folder, a single spreadsheet contains all the information in separate sheets. In more detail: (i) The “Introduction” sheet presents the structure, the nomenclature used, and the contents of the spreadsheet; (ii) the “1. Structure” sheet shows the geometry of the asset along with an overview of the developed numerical model; (iii) the “2. Modal_Analysis” sheet presents the results of the structure’s modal analysis in terms of eigenmodes, eigenperiods, and damping ratios, (iv) the “3. Damage_States” sheet shows the considered damage states, along with the EDP and the corresponding capacity checks, (v) the “4.1.*. IDA_PGA_**” and “4.2.*. IDA_AvgSa_**” sheets list the IDA results from both IMs (  and ) considered per  (* denotes the number of the  and ** denotes its name); (5) the “5.1. Fragility_PGA” and “5.2. Fragility_AvgSa” sheets present the calculated empirical-CDF fragilities, which are also plotted for illustration purposes in the “5.3. Fragility_Plots” sheet.
