PEER Loss Estimation Toolbox

E. Miranda & C.M. Ramirez PEER Annual Meeting Jan. 19-20, 2007

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

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

Brief description of the toolbox

1. Seismic hazard module

MAIN FUNCTION:

Allows users to import and visualize site-specific seismic hazard curves.

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.

OTHER FUNCTIONS:

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 built-in component fragility and loss functions

• Import and visualize story-loss functions or component fragility and loss functions.

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.

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

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)

How does the toolbox facilitates getting to a larger audience

• Will be accompanied with a PEER report that provides full documentation on how to use it with easy to follow step-by-step instructions

Documentation

• Will be easy to distribute via email, website download, ftp download, etc.

Distribution/

Dissemination

• Will be accompanied with two fully documented examples, that user will be able to reproduce for facilitating its use
