If you have an A36 bar 1" wide and 1-1/2" deep. 29" long between a hinge and a pinned latch. What force is required to permanently deform the bar, in the strong axis, by 7/8" at the center? The load is applied by a point at center span.

A large machine requires a foundation of concrete piers that support it off of the ground. The machine Vendor supplied seismic loads at the equipment attachment to the piers per ASCE 7 Chapter 13 Nonstructural Components.
The engineer designing the concrete piers has stated that they require...

If you put the vertical straight edge at the crease, do you exceed the horizontal weld seam deviation? Idea on how the crease occured? If your certifying as API 650, and you deem it within the allowable deviations, then it is ok. If you feel it deviates outside the allowable tolerance, then...
Define service test, do you mean a startup test of filling with oil? API 650, Chapter 7 Section 7.3.5 allows for an alternate to hydrotesting if water is not available. This is something the purchaser would have to approve. Open some communication with the contractor, ask them for the...
Grout holes should be in larger base plates, my expereince is a base plate over 2'-0 square gets (2)-1" dia. holes near the web of the column. Assuming your bolts are on the corners of the plate or outside the flanges of the column. This allows for reducing air entrapment, especially if you...
Can anyone provide guidance in the form of a detail, or description of the best way to pour an elevated slab against a steel column? Is a piece of joint material between the two sufficient for expansion, should there be joints around the area for cracking?

Is there an industry standard for welding a carbon steel slip on flange B16.5 to carbon steel pipe, STD weight? What, if any, specification or code describes this? I understand that typically these are fillet welds, one outside of the pipe to the back edge of flange, and one inside between the...
Thanks, some of your posts were useless, and others much help. For the record I 'll clear it up, their are four newbies, four middle class, and five senior engineers. Three women are correct, I was not one of them. So 13 engineers. Not that this makes much difference, but I should have known...
My department consists of a dozen engineers. Three women. Six senior engineers, all male. Three newbies, all male. And the rest of us are middle class, including the three women. Two of the women have more experience years than I.
Our manager recently decided to have four persons attend a...
Are you the bidder? Your supply of the design would make it appear so. If so, where is the structural engineer that designed this structure? He/she should be able to create an erection specification.
I am unable to discern your design, when you say longitudinal beams? Are you trying to say...
304 plate is covered in ASTM A240, as far as property minimums go, 30ksi yield and 75ksi tensile. I do not believe there is an ASTM covering rolled shapes of stainless steel. Though there is a company or two that rolls 304 shapes.
