WELD GROUP ANALYSIS PROGRAM

“WELDGRP” WELD GROUP ANALYSIS PROGRAM
Program Description:
“WELDGRP” is a spreadsheet program written in MS-Excel for the purpose of analysis of weld groups using
either the ultimate strength method (also known as “‘instantaneous center of rotation” method) or the “elastic”
(vector) method (“Alternate Method 1” in AISC Manual). A separate worksheet contains data tables for welds.

This program is a workbook consisting of eleven (11) worksheets, described as follows:
