Good Evening,
I hope you're doing well. For my project, I am looking to connect two hydraulic cylinders (3-inch OD) with a 16-inch OD flange, as shown in the attachment. The clamps are intended only for lateral bracing of cylinders, as the face plate at the top of the cylinder is connected to a...
Good Morning Fellow Engineers,
I have a beam with multiple closely spaced roller supports (shown only 4 in attached pdf but I have 12 in total) and a cantilever at one end. Design intent is to move the beam on rollers with hydraulic cylinder on one end. When I try to calculate the reaction...
Good Morning Fellow Engineers,
I'm working on a project with multiple full-length transverse stiffeners & doublers welded along the beam. Original Plan was to weld continuously on all sides—across both flanges and the web. However, I'm concerned about potential warping due to the extensive...
Good Morning,
I hope you are well. I am working on sizing an isolation UMHW pad that will be placed below a beam subjected to a load of 250 kips (as shown in attached PDF). Based on the triangular load distribution principle, I expect the load to be distributed over a certain area. My original...

Good Morning Fellow Engineers,
For the overhead beam, I’ve been asked to provide a rated load tag. I plan to base the rating on CMAA guidelines, as using a beam trolley or clamp attached to the bottom flange and concentrated load on the middle likely represents the worst-case loading scenario...
Good Morning Fellow Engineers,
(File attached)
For calculating the lateral-torsional buckling bracing, AISC Appendix 6 specifies minimum requirements for both flexural strength about the longitudinal axis and flexural stiffness.
- Yura provides the formulation for calculating the stiffness...
Good Morning Fellow Engineers,
I am working on a structure with two W40x324 beams spaced 10 feet apart, each carrying a concentrated load of 150 kips at mid-span on the top flange (attached file showing AISC, YURA reference and loading condition) . My goal is to prevent lateral-torsional...

Good Morning Fellow Engineers,
I am trying to determine the generated reaction loads at bolted joints when a horizontal force acts on center of gravity of machine (Seismic Loads).
My original Intent was to use the following approach
-Create a coordinate system at COG of machine
-Create a...
Good morning fellow engineers, I hope you are doing well
1st: I am trying to simulate a fixture as shown in attached file. Eventually I would like to find reaction loads / moment at fixture and thus selecting isolator based on that. Any ideas on how I should proceed?
2nd: Is it possible to use...
Good Evening fellow engineers,
I have recently received my engineering stamp and am curious about liability issues while stamping the layout drawings. I work with an elevator contractor. In the first phase, we usually issue the layout drawings showing the technical data table, plan view &...
Good evening fellow engineers,
I am looking for information regarding the swivel joint marked up in attached PDF. Is it just a hollow pipe with bolt going through it? or is it usually a pin inside a bearing and further enclosed inside pipe? Any information or breakdown of that joint will be...
Good Evening fellow engineers,
I am looking for some information about the slot length. I understand that CISC/AISC has tables which set a limit on length of slots. However, I see a lot of parts by different suppliers (sheet metals, steel plates, angle etc.) with really long slots. Having a...
Good evening fellow engineers,
I am working on a project where I need to provide a 6' long beam with a capacity of 1 tonne (short load duration). As a beam trolley will be used on the beam, I will be following CMAA. The beam will be attached to ceiling(8in concrete) with post installed anchors...
Hello guys,
I am designing a steel plate (which will be welded on all four sides) and load will be acting at 8 location (uniform load acting over a small circular area, represented by the blue circles). I was planning to use Roark's formula 8b (also shown in attached file) but it only works...
Good morning guys,
what are the best practice while adding shims? In my case, I have a beam structure which will be sitting on HSS. I have to raise the structure by 2in. I could add additional plates (holes in center of plates and then plug welds) but I would like to know how does experienced...
Good Morning fellow engineers,
I am working on a project where I have a fillet weld under eccentric loading as shown in attached file. Initially I was following

and doing my calculations based on that (calculate direct and secondary shear...

Good Morning fellow engineers,
I am working on angle bracket design which will be attached to concrete wall with expansion anchor bolts (as shown in attached PDF).
Here is what I am planning to do.
As there is a eccentric out of plane load acting on bracket, it is going to try to pivot about...
