Clean Columns
With Clean Columns the user can quickly find the minimum weight column section that can be used without stiffeners and/or doubler plates to develop a specified moment, based on the criteria presented in AISC Design Guide 13, Stiffening of Wide-Flange Columns at Moment Connections . Once the joint forces are known, this tool takes only a few minutes to identify the lightest unreinforced column section. The tool applies in wind or low-seismic applications. You must enable macros in MS Excel for this program to work. Note: security has been removed, so this file is user-modifiable if you are sufficiently skilled with Excel programming & scripting. This tool was originally published as an AISC Steel Solutions Center 'SteelTool'. AISC no longer technically supports and maintains these files. Therefore, it is availale to any user 'unlocked' for those to freely update and modify on their own and post to their own profiles.

Newly revised for the 2010 AISC Specification, this utility calculates the minimum weight column section that can be used without stiffeners and/or doubler plates. Applies in wind or low-seismic applications, and is based upon the 2010 AISC Specification, the 14th Edition Steel Construction Manual, Design Guide #13, and Design Guide #4 (2nd Edition). You must enable macros in MS Excel or this will not function.

This spreadsheet calculates the rotated section interaction diagram of a column. It can be used for columns with an embedded structural shape or without it. It is limited to I and rectangular HSS structural profiles.
This spreadsheet uses the strain compatibility method to calculate the strain linear distribution using the concrete compressive strain at 0.003 per ACI-318-14/19 Sect. and AISC Sect. I1.2b.
This tool provides analysis of HSS sections in accordance with AISC 360-22, LRFD specifications. It includes ASTM 500, Grades B and C, and ASTM 1085, Gr. A, the latter allowing use of the full section properties. Square and rectangular sections are included, but no round sections. Crane loads may be included in the analysis, with the load being applied to the 'web' of the member creating a moment at the top and which linearly drops to zero at the base of the column. Moments about both axis, shear, and torsion are included.
This spread sheet calculates W type beam to HSS column connection. We can use this type of connection when the other type are not able to transfer the factored moment The reference used in the attached spread sheet is "Hollow Structural Sections-Connection Manual-AISC Copyright 1997. The example in this reference is in LRFD format and imperial units. I used metric units and the Canadian database is attached. The limit states are those indicated for the "Cut-out plate connection" which is very similar connection to this described here. This tool is not password protected in order to give the possibility to make minor changes. Obviously you can protect the spread sheet leaving the input cells(in red) not protected.This workbook contains 3 sheets. 1. Input & results, 2. Canadian database, 3. Sketch -could be printed and give it to the draftperson. This tool must be used only by professional engineers after thorough verification. I designed the tool of my best knowledge but I dont assume any responsibility in case of errors.
Stepped column analysis for determining effective lengths and effective length K factors. These types of columns and configurations are most often used in mill-type buildings involving bridge cranes. While the material is a bit dated, this tool should still prove useful for estimates of required stepped column sizes and configurations.
