"BOLTGRP" Program

Doc"BOLTGRP" --- BOLT GROUP and BOLT STRESS ANALYSIS PROGRAMProgram Description:"BOLTGRP" is a spreadsheet program written in MS-Excel for the purpose of analysis of bolt groups usingeither the ultimate strength method (also known as "instantaneous center of rotation" method) or the "elastic"(vector) method ("Alternate Method 1" in AISC Manual). There is also a worksheet for bolt stress analysis, and aseparate worksheet that contains data tables for bolts.This program is a workbook consisting of thirteen (13) worksheets, described as follows:Worksheet NameDescriptionDocThis documentation sheetTable XIBolt group instantaneous center analysis for one row of boltsTable XIIBolt group instantaneous center analysis for two rows spaced at 3"Table XIIIBolt group instantaneous center analysis for two rows spaced at 5-1/2"Table XIVBolt group instantaneous center analysis for two rows spaced at 8"Table XVBolt group instantaneous center analysis for three rows spaced at 3"Table XVIBolt group instantaneous center analysis for three rows spaced at 6"Table XVIIBolt group instantaneous center analysis for four rows spaced at 3"Table XVIIIBolt group instantaneous center analysis for four rows spaced at 4"Bolt Group (= 1.0Horizontal Load, Ph =0.00kipsPv=57 k8Ca =N.A.Ca = (Ca/Co)*CoNo. Bolts in Vert.
