Can you advise on what the most appropriate standards (for the loads and structural design of moveable equipment) to cite should be when writing specifications to procure a fabricated piece of equipment in the US such as a moveable stack-out or recliamer, or a traveling gantry used for loading...

I need some help understanding how to interpret the limits of clearances shown in Table 5 of ASME 4.1 "Preferred Limits and Fits for Cylindrical Parts". For a 5.50" diameter pin (forming a hinge pin that goes into a bushing), with a Class RC 7 fit, it appears Table 5 indicates the ID of the...
I welcome some suggestions on a metallurgy question about which stainless steels specifications would be most appropriate for some manufactured hinge pins. My project is 99% structural using carbon steel, of which I am very experienced, designing heavy industrial structures, flood walls, and...
I am looking for a good source to define recommended tolerances for welded steel fabrications (large steel flood gates), something I can cite in the project specification I am writing to impose practical limits on the final product. Most of my prior experience has been with structural steel...
We have a question about how to properly model a sheet pile wall for a total stress analysis, particularly where the tension zone is to be ignored.
We have a cantilever sheet pile wall with the soil at the same height on both sides that is to be designed for holding back a still pool of water...
Will it likely pose a problem to remove the ventilators on the top of a commercial building. We have a 40 year old commercial building that will soon get a new roof (changing from a built-up roof system to a simgle ply membrane roofing system). The roofing contractor suggested removing the...

Should we particularly be concerned with either brittle fracture or any other similar issues in the use of ASTM A572 GR 50 plates in the design of some large structural bins and hoppers for coal storage. It will be located in northern US climates. As a structual engineer, we are most familiar...
We are trying to confirm the stability of a vessel made with SA-516-70N which will have girth welds PWHT to 1200 deg F. ASME Section II, Appendix 3 give some insight on calculating allowable stresses at various temperatures. At higher temperatures, it seems to be governed by the Creep/Rupture...
