The client had us do away with a tie-off system we proposed for the top, and asked us to design it for without. So, there would be flagpole, cantilever action, although the expected lateral loads at the top would only be wind load on the wellhead 'christmas tree', about 1 kip. But, we have no...

Here's the Excel version. As to be expected, no warranties written, expressed, or implied about the accuracy, etc. Do let me know if you find any errors. I wrote it because the equations for dynamically sensitive structures are so...

If you use ASCE 7-05, you might find this MathCAD file useful.... I wrote an Excel spreadsheet version, too. It's based on ASCE 7-5 Section 6.5.8.2.http://files.engineering.com/getfile.aspx?folder=8a9adea8-b418-4724-bcb6-8f78e7b52908&file=ASCE7-05-Section_6.5.8.2-Gust_Effect_Factor.xmcd

This is for an oilfield project where the client (an oil company) has a corroding 10" diameter production casing inside the 20" diameter conductor casing. The wellhead sits on top of the casings, and the client wishes to excavate the 20" casing, cut windows into it, and access the 10" interior...

I have been asked to strengthen a round pipe that will have three symmetrical ‘windows’ cut into it on 120 degree centers, with wide-flange shapes welded to the outside of the pipe section as pictured in the attached photo (I'll try to make the screenshot attach). The goal is to provide at...

I've since gotten some help from a local professor who has a cool website on this exact issue, too: http://www.bgstructuralengineering.com/BGSCM/BGSCM008/Design/BGSCM0080602.htm

Thank you to StructuralEIT, jberg, jike, and JAE for your answers and input. JAE, I found in the AISC Steel Construction Manual, 13th Ed., page 16.1-63 under F13.3 some minimum lengths that the cover plate should extend beyond the theoretical cutoff point, depending upon the weld configuration...

Can anyone recommend a design guide or go-by for determining the weld or stitch weld needed to attach a single bottom cover plate to a wide flange beam? I've found just a little bit in Omar Blodgett's "Design of Welded Structures", but not much more. Additionally, I have a problem with a...

I have a long, narrow structure with 10 frames each with three supports. To allow for growth of the structure due to temperature loads, I want to model 3 supports on one end as 'pinned' and the other 27 supports released to provide vertical and transverse resistance as well as longitudinal...

I am trying to determine what the "h" value is in the beam properties tables (Compact Section Criteria column) in "Part 1 Dimensions and Properties" of the AISC Steel Construction Manual, 13th Edition. Its value, taken by multiplying the listed "h/tf" by "tf", doesn't seem to correspond with...
