"BOLTGRP" --- BOLT GROUP and BOLT STRESS ANALYSIS PROGRAM Program Description: "BOLTGRP" is a spreadsheet program written in MS-Excel for the purpose of analysis of bolt either the ultimate strength method (also known as "instantaneous center of rotation" metho (vector) method ("Alternate Method 1" in AISC Manual). There is also a worksheet for bolt separate worksheet that contains data tables for bolts. This program is a workbook consisting of thirteen (13) worksheets, described as follows: Worksheet Name Description Doc This documentation sheet Table XI Bolt group instantaneous center analysis for one row of b Table XII Bolt group instantaneous center analysis for two rows spaced Table XIII Bolt group instantaneous center analysis for two rows spaced a Table XIV Bolt group instantaneous center analysis for two rows spaced Table XV Bolt group instantaneous center analysis for three rows space Table XVI Bolt group instantaneous center analysis for three rows space Table XVII Bolt group instantaneous center analysis for four rows space Table XVIII Bolt group instantaneous center analysis for four rows space Bolt Group (<=25) Bolt group elastic analysis for up to 25 total bolts and 4 loa Bolt Group (<=75) Bolt group elastic analysis for up to 75 total bolts and 8 loa Bolt Stress Bolt Stress Analysis for H.S. Bolts subject to tension and/o Bolt Data Bolt Data Tables Program Assumptions and Limitations: 1. The AISC eccentric loads on bolt groups worksheets (Tables XI through XVIII, pages 4-62 applicable for only in-plane shear loads and torques (moments) on the bolt group. 2. The elastic method worksheets, "Bolt Group(<=25)" and "Bolt Group(<=75)", can be used f in-plane and out-of-plane loads on the bolt group, or where geometry limitations of th through XVIII are ecceeded. The "elastic" method (AISC "Alternate" Method 1) will alw results when compared to using the AISC Tables. 3. The elastic method worksheets, "Bolt Group(<=25)" and "Bolt Group(<=75)", assume a mini and a maximum of either 25 or 75 bolts for a bolt group. 4. The elastic method worksheets, "Bolt Group(<=25)" and "Bolt Group(<=75)", assume that a contribute to the moment of inertia of the group, and the applied loads are linearly d based on the location of the bolts from the centroidal axes. 5. The elastic method worksheets, "Bolt Group(<=25)" and "Bolt Group(<=75)", assume an ort coordinate system. All bolts and loads points MUST BE located in the "positive" (1st) bolt or load point location coordinates are NOT permitted. "Right-Hand-Rule" sign con applied forces and moments at load point locations. 6. In the elastic method worksheets, "Bolt Group(<=25)" and "Bolt Group(<=75)", the bolts numbered in any desired order. However, the user should make sure to either clear the spreadsheet cells that are not used for input or those cell values should be input = 0 MUST BE input in proper numerical sequence with no "breaks" in the numerical order of 7. The "Bolt Stress" analysis worksheet checks allowable bolt tension and bolt shear again High strength bolts from 3/4" up through 1-1/2" diameter are assumed. Effects of fati required. Bolts can be in either single or double shear. AISC 9th Edition Manual (AS
