Shaft Capacity Calculation Spreadsheet
Clean Columns was developed to return the lightest column section that can be used without stiffeners and/or doubler plates to develop a specified percentage of a selected beam’s plastic moment capacity, based on the criteria in AISC Design Guide Series #13 and the 2005 AISC Specification for Structural Steel Buildings.
The design of the column for axial load capacity is not considered.
Column load take down & design for symmetrically reinforced rect columns bent about two axes.
