PEER Loss Estimation Toolbox Eduardo Miranda C. Marc Ramirez Stanford University PEER Annual Meeting - Thrust Area 1 Meeting Jan. 20th, 2007 PEER Loss Estimation Toolbox Main goal of the toolbox Development of a user-friendly computer tool, referred to as PEER Loss Estimation Toolbox to conduct seismic performance assessments of individual buildings. In particular the toolbox is aimed at conducting seismic loss estimation providing various quantitative measures of economic and downtime losses in individual buildings. E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox The PEER loss estimation toolbox has five main modules: 1. Seismic hazard module 2. Story loss functions module 3. Response simulation module 4. Loss estimation module 5. Disaggregation and visualization module E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox 1. Seismic hazard module MAIN FUNCTION: Allows users to import and visualize site-specific seismic hazard curves. OTHER FUNCTIONS: Based on geographic coordinates at a site obtains the USGS seismic hazard curve at the site and provides two simplified procedures developed by PEER to modify it to account for local site conditions. E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox 2. Story loss functions module Allows users to: • Select built-in story loss functions for common building types • Compute story loss functions using component fragility and loss functions built-in • Import and visualize story-loss functions component fragility and loss functions. E. Miranda & C.M. Ramirez or PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox 3. Response simulation module Allows users to import and visualize results of response simulation (e.g., incremental dynamic analyses) computed with OpenSEES or other simulation platforms. E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox 4. Loss estimation module Performs all economic loss estimation calculations and simplified downtime estimations. E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox Brief description of the toolbox 5. Disaggregation and visualization module Performs disaggregation calculations and provides various tools to visualize results. E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox How does the toolbox facilitates getting to a larger audience • It is a MS Excel-based tool that practically all people have so does not require acquiring/learning a new software package E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox How does the toolbox facilitates getting to a larger audience • It has a very user-friendly graphical user interface E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox How does the toolbox facilitates getting to a larger audience • It has online “tip text” as one passes over the various interface objects to facilitate learning its use E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox How does the toolbox facilitates getting to a larger audience • It allows easy-to-use “copy-and-paste” data stored in other Microsoft products (e.g., a seismic hazard curve stored in a different Excel file) E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007 PEER Loss Estimation Toolbox How does the toolbox facilitates getting to a larger audience Distribution/Dissemination • Will be easy to distribute via email, website download, ftp download, etc. Documentation • Will be accompanied with a PEER report that provides full documentation on how to use it with easy to follow step-by-step instructions Examples • Will be accompanied with two fully documented examples, that user will be able to reproduce for facilitating its use E.
