Analysis & Design of Weld Groups
Description
Excel Template for the Analysis & Design of Weld Groups Subjected to Simultaneous Shear, Bending, Torsion & Axial Loading. Weld configuration can be any shape of multi-linear weld lengths in a plane. If present, unsymmetrical bending is taken into account in the analysis.

The updated calculation has an option to find stress resultant using SRSS OR EuroCode (Von Mises) formula.

Perhaps I'll try the "back door" as suggested by AFingle. I'll also check the other suggested resources, but I'm looking for a tool (SI units) that uses the von Mises approach for combining shear and direct stress, as that is what the design rules (Australia, AS3990) use to establish stress limits.
1) WELDGRP.xls - One of Alex Tomanovich's great spreadsheets. They are protected but not with a password. Just download and unprotect worksheet. There are elastic and ultimate strength methods. A metric version can also found here WELDGRP Metric.xls.
2) LineSec.xls - This is good for any section made up of lines, welds lines included. I find it useful because the weld line does not have to be the same thickness each line can have its own thickness property. Analysis is elastic. This calculation is mine and all the working is shown with XLC equations so it should be easy to modify.
3) ThinWallProp1.xls is a great calculation from Yakov Polyakov. This will give the ultimate strength of a weld line. From memory I think all lines have the same thickness.
One or other of these methods has got me out of all the weld static strength problems I have encountered.
Any ideas anyone?
