Introduction

Performance Assessment Calculation Tool (PACT) is the computational companion to the ATC-58 35% Draft Guidelines. PACT provides a user-friendly platform for scenario-based, intensity-based, and time-based loss calculations. It can accommodate results obtained from nonlinear response history analyses as well as simplified analyses.

PACT provides three basic but integrated functions:

1. Gathering and organizing building information, fragility functions and demand parameters;
2. Performing loss calculations using the PEER PBEE methodology; and
3. Providing overall and performance group specific loss information obtained from the above calculations.

The PACT user interface is coded in Microsoft Visual Basic and its computational engine is coded using a mixture of FORTRAN and Visual Basic routines.

NOTICE: This software has been prepared by the ATC-58 Project Team to assist interested parties in obtaining an understanding of the methodology as it is being developed, and to facilitate comment and feedback to the project team on its further development. The data included in this software are incomplete at this time, are not necessarily appropriate for use in actual projects, and should not be used for that purpose. This software will be subject to further revision and enhancement as the methodology is completed in future years.

Hardware and Software Requirements

In order to use PACT you need a PC with the following minimum software and hardware:

Click here to download the 35Mb ZIPed file PACT.zip, containing the PACT software. Select the option: Save to Disk, and save to any temporary folder on your PC. As of 6/20/07 a patch has been issued for PACT Beta version 1.0. First-time users must first follow the installation procedures below to install PACT Beta before installing the patch.

Create a temporary folder (named PACT in the example below) on your PC and unzip the files and folders into it. Be sure to preserve the directory structure in the ZIP file. At this point you may want to review the PACT Beta Quick Installation Guide PDF file, which contains an electronic version of these instructions.

Then double-click Setup with the red cube to its left.

The installation process begins and you will see the following screen:

Click "System" to check system compatibility. Your need a Windows 200, XP, or later for PACT-Beta to work. Once you have clicked “System” the “INSTALL” button becomes available.

Click "INSTALL" and then make sure you install both the Program and the Data. Installation of the program and data may take several minutes. Please follow the instructions during the installation and click "Exit" at the top right hand side once both the program and data have been installed.

Installing PACT Beta Patch

Download the 800 Kb executable file update.exe, containing the patch for the PACT Beta software. Select the option: Save to Disk, and save to any temporary folder on your PC. Simply double-click the downloaded file and the patch will install itself automatically.
