This document has been prepared in accordance with information made available to the American Institute of Steel Construction at the time of its preparation. Therefore, it is availale to any user 'unlocked' for those to freely update and modify on their own and post to their own profiles. AISC no longer technically supports and maintains these files. This tool was originally published as an AISC Steel Solutions Center 'SteelTool'. Note: security has been removed, so this file is now user-modifiable if you are sufficiently familiar with Excel programming & scripting. You must enable macros in MS Excel for this program to work. The program will also allow the user to input a design moment and unbraced length and give the lightest sections that are adequate, from the list of user-selected shapes.
The program will plot the curves for any set of user-selected cross sections. (Metric units version) (Note: I also have an English units version of this workbook in a separate post.) The plot includes the beam weight, which should be deducted when calculating the maximum uniform load the beam will support.Īnalysis of single-span beams and continuous beams up to 5 spans. The strong-axis available flexural strength (both in ASD and LRFD) is plotted as a function of unbraced length, Lb, for W, C and MC shapes. AUTHOR MAKES NO GUARANTEE AS TO IT'S CORRECTNESS OR ACCURACY.Īvailable_Moment_vs_Unbraced_Length_per_13th_Ed._Manual.xls Spreadsheet accepts varying girder spacing, although not recommended for constructability. This bridge has fascia beams: if your bridge does not be sure to modify spreadsheet to include ballast retainers in dead load list. Works for curved bridges: Should also work for tangent bridges but be sure to check. Live Load Deflection calculated for Alternate Load only which controls for spans 50' or less. steel only carries steel and concrete, partial composite for remaining dead load, full composite action for live loads.).
