Weld Design

Weld Design

(OP)
From time to time I have the need to design a few welds. Is there softwar available to help on this? I have been using the steel Handbook tables.

RE: Weld Design

ajk1...not sure of any software, but Blodgett's book is excellent for this.

RE: Weld Design

Ron,
The Steel Construction Manual tables 8-4 thru 8-11 use the instantaneous center of rotation method (plastic). I only recall seeing the elastic method in Blodgett's book. While it is fairly easy to use hand calculation for the elastic method; tables, a spreadsheet or other software is probalably more practical for the instantaneous center of rotation method. The only example calculations for the instaneous center of rotation method that I have found is in Salmon and Johnson's text. I would like to see other examples if anyone knows of any.

RE: Weld Design

ok, thanks. A bit surprising that there is no software to do this ann speed up the process.

RE: Weld Design

Weld design is difficult to resolve in a broad software package. We write our own connection design software, and certainly include the weld design in each case. The eccentricities and force combinations are difficult to program without more perspective. With all the years of program development we have still have special conditions that require research and hand calculations.

Alex Tomanovich has a spreadsheet here.

Alternatively, another spreadsheet is here. Look for WeldCalc spreadsheet.

RE: Weld Design

links in AISC's steeltools ... I myself need to update my downloads from the site.

RE: Weld Design

I checked out Alex Tomanovich's spreadsheet. Unfortunately it is ASD with unfactored loads. In Canada pretty well all design has beem Limit States Design using factored loads since about 1977. Guess I will just have to use the CISC handbook Tables for the time being.

RE: Weld Design

Yakpol.net has a shareware spreadsheet that calculates weld group capacity using the instantaneous center of rotation method and the elastic method. yakpol.net/
