Steve – I’m off to bed now (Sydney time is 10 hours ahead of GMT (+9 UK summer time), but if you send me an e-mail to dougaj4 at gmail I’ll send contact details.

Thank you, I am trying to edit the SSSpan worksheet as this best suits the side frame of a blast resistant door. Can I call you to discuss a few questions?

Regards

Glad you found it useful Steve.

Feel free to ask if anything isn’t clear, or suggest improvements and/or extensions.

Thank you for posting such a useful tool. I was wondering how to get excel to add multiple loads on a SS-beam (analysis of a blast resistant door frame) at varying locations and realised the Macaulays method was probably the best way of evaluating the BM from which I could undertake a SDOF analysis of the door as a whole. Your spreadsheet will be invaluable.

Re.: Goal Seek on multiple cells:-

There is not quite enough explanation for me – I am lost.
I have formula, similar to, but a little more complicated than: z = 1/(sqrt(H^2 + (A-x)^2 + (A-y)^2).
If I can understand the operstion for this situation, I should be able to solve my real problem.
A is a fixed but chosen number.
z is a fixed but chosen number.
x ranges say from -10 to +10 in increments of 1.
y ranges say from -10 to +10 in increments of 1.
I would like to find the value of h at each coordinate (x,y) that produces the required constant specified value of z.
And produce a spreadsheet of the values of h for each coordinate (x,y).
Is this description succinct enough?
From your description, I suspect your macro will do the trick.
But I need detailed step by step help!

John Pollard

The axial force is applied at the centroid of the concrete section, but if the section is cracked, or the reinforcement is not symmetrical, then the centroid of the reaction force is not at the centroid of the concrete section, so if the applied axial load is not zero this creates an additional moment.

If the axial force = N, applied moment = M, depth of NA from top face = Dna, and depth of section = D, then the total applied moment about the neutral axis =
M + N(Dna – D/2)

If you use that revised moment you should find that M/C = EJ (where J = 2nd Moment of Area), for any value of axial load.
