Moment-Area Spreadsheet

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There are free spreadsheets that do this at 
http://www.microstran.com/freestuff.htm . Beam.xls is for a single 
span beam and Beam2.xls is for a two-span continuous beam.

>If all you're interested in is analyzing simple beams, you can use the moment area method 
>and not be bothered with all the matrix analysis and ctrl-shift-enter stuff.  This is the method 
>that the beam analysis components in Enercalc use.  I've created a spreadsheet to do simple 
>beams with point, uniform and trapazoidal loads.  It calculates moment, shear and deflection.  
>The method involves breaking the beam into 100 or so pieces and performing analysis on 
>each segment.  I believe Blodgett has a section on how to do this.  Also, there used to be a 
>spreadsheet on Structuralist.net that did this, but I just looked and couldn't find it.  I think 
>this method could also be used for continuous beams, but I havn't tried to do that yet.
