Steel beam spreadsheet 1

[JohnBreen]

Hello all,

I have a gazillion cantilevered pipe supports that are fixed to concrete floors and concrete walls (hilti bolts). They are all made from standard AISC rolled shapes of varying lengths. I can assume that these are "anchored". I want to QUICKLY go through them and calculate their stiffness (spring rate on two translational axis) and their natural frequencies.

Has anybody ever done an Excel spreadsheet to do this. It would really save me hours of work. Sadly, I am not an Excel guru.

Thanks, John.

If you can write the formulas by hand and understand the engineering, it is easy to write a basic Excel spreadsheet to automate this.

For example, if you need to calculate bending moment of simple beam, length can be input in cell A1. Uniform load in cell A2.

The moment can be calculated in cell A3 by writing:
=A2*A1^2/8

Asterisk is multiply. Carat^ is exponential. Slash / is divide. If you have more than one number in denominator, you use slash repetively...example: F/d/r/e is F divided by (d*r*e)product.

You could also write that as: F/(d*r*e)
