2D Frame Analysis
(4/11)
Description
Analysis of a 2D frame subject to distributed loads, point loads and moments
Applied Loads
For distributed loads specify length from the ends of the start and end of the load, and the load intensity at the start and end.
For Point loads and moments specify the position and magnitude
Positions and load lengths are measured along the beam axis, as a ratio of the beam length.
Distributed and point load direction is either "X" (horizontal) or "Y" (vertical)

Doug, thanks for the reply. As you say it should be easy enough to setup alternative loadcases, copy them into the analysis, grab the results and report them elsewhere.
Another possibility for the problems opening the file is the file uploaded to ExcelCalcs, is incomplete. Doesn't appear to be much built-in error checking in the file transfer process.
The other day I downloaded the upgrade for Multiframe and only got 3% of the file with no warning. So my internet connection does not appear to be overly reliable.

All loads entered on the load sheet will be treated as a single loadcase, but it would be fairly easy to set up separate loadcases elsewhere and run them separately and combine the results the way you want.
I will be doing some more development of this program in the future, but I have quite a few other projects occupying my time at the moment, so I don't know when I'll get onto it.
I think it handles one loadcase at a time but I think the worksheet could be modified.
1.2G + 1.5LL (liveloading)
0.9G + WL1 (wind uplift)
0.9G + WL2
0.9G + WL3
0.9G + WL4
1.2G + WL5 (wind downdraft)
etc...
So that can then find the maximum. Rather than having one workbook per loadcase which appears to be the typical approach.

Conrad
