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.

Just to close off; the recent submission of an updated file by the Shaiq Khan has resolved the issue. The spreadsheet is now fully functional and does just what I need. Thanks!

Thanks.

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

Phil this is a useful resource it may be what you are looking for:
Biaxial Stress Assessment.xls

Thanks for the reply John. The cell I need to change is actually provided as an option for the user (as a drop-down box), but (perhaps inadvertently) has been locked so that the drop-down selection cannot be changed.
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.

Excel protection is so easy to break it is barley worth setting. A google search will show 1000's of pages outlining how to break them. See Gimpsey and Associates solution - passwords hacked in the blink of an eye.

technouk spreadsheets are generally password locked which keeps them safe from modification but difficult to modify for your own needs. There are a couple of other repository items which I think you will find both useful and easy to modify:
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.

This spreadsheet looks to be an excellent resource. I can't seem to change the Equivalent Stress Calculation Method from SRSS to Von Mises (cell is protected and sheet has password protection).
Any ideas anyone?

British standards, but an excellent resource.
