Calculation Preview



This spreadsheet is to be used to check the adequacy of roof purlins for a specified combination of loads. The designis based on the maximum yeild strength (Mn = FySx) as stated in the AISC Manual 13th Ed. This spread sheet can only be used for load combinations with two variables. In most cases the worst case scenario is 0.6DL+W, so this should be adequate. Only the values in the highlighted cells need to be changed.

It looks like the Dead Load and Wind Load values are reversed in the formula in E32. Or another way of looking at it is that the labels in H21 & K21 are reversed.

Also, since wind uplift is the usual condition, the bottom flange is the compression flange, and cannot be assumed to be braced, so the lateral-torsional buckling statement is incorrect.

Yes it is. I'm starting off simple. By the way, in structural reports, is it more desirable to have all working shown or will results in tabulated format with code cited in the reference column be adequate.

My aim is to develop spreadsheets that only need to have the input changed and then printed out.

So simple. Nothing is new.
