I understand the basic prying concepts and calcs. However, I am connecting this monorail under two beams and this version of prying came to mind. Does this practically exist or does the stiffness of the monorail/web prevent meaningful prying in this manner? I figure the flange/web would "flex"...
I was talking to a home builder buddy of mine and had an interesting conversation. He showed me a soils report (sealed by a geotech engineer) and the soils are expansive (Texas clay). Geotech recommended drilled shafts for the grade beams (with suspended slab) or 8 feet of engineered fill to...
I am designing a platform that is supported on two sides of a concrete pier via a cantilevered ledger. Regarding the top member axial shear, would it be a fair assumption that all three anchors share it equally similarly to a regular bolted connection design?
(Also, ignore some of the other...
I'd like to evaluate a cyclone separator with a short cone (compared to Perry's 2xDia length recommendation). Does anyone have any guidance on how this performs compared to a longer cone? https://files.engineering.com/getfile.aspx?folder=e8a019a4-98c8-4ce9-9dea-06f4bbb62df8&file=Separator.png
My question is related to industrial process plant design and engineering.
I understand that early on in the engineering process pumps are roughly estimated in order to provide cost estimates and to beat lead times. My question is how are they sized before system pressure drop is known? What's...
I am trying to model a tangential nozzle on a conical transition as shown on the attached snippet. I can do this easily on a cylindrical shell, but it doesn't seem to have the option on a cone. Can someone confirm if the software can or cannot do...
Per attached example you would use total load in all 3 bents to plug in to bracing stiffness equation even though both ends of structure are braced. The way I understand this is that each bracing member is designed for 2X the load it would theoretically see instead of 1X load (i.e. each braced...
Through a professional relationship I have been offered the opportunity to open an satellite office for a relatively young engineering firm (5 years old). The main firm has about 35 employees and caters to mostly O&G/petrochem - revenues somewhere around 7-8 mil. The overall business is growing...
I am working on gaining a better understanding of the operation of towers and am reading through "A Working Guide to Process Equipment".
My question is on the attached photo:
Feed flow rate of 10,000 lb/hr of 90% Water and 10% Alcohol
Heavy flow rate of 9,000 lb/hr of water
Light flow rate of...
I am doing some self-learning of wind loadings and had a question regarding some outputs I am looking at. When it comes to the various roof/wall area loadings do you pick the highest (or most negative) worst case scenario value to apply to that area?
For example (see attached) for zone 3r...
Designing a motor foundation with rough dimensions of 104" long, 39" wide, and 11" tall. Designing as plain concrete pedestal with T&S reinforcement of .0015Ag. The pedestal is on a concrete slab so interface minimum steel area is .005Ag. Using 26 #8 dowels for that, but wanting to get around...
When designing column stiffeners for a gable rigid frame, for analysis to reflect design should the stiffeners be parallel to the beam flanges or can they be perpendicular to column flanges? See attachment for...
I am tasked with designing a motor/pump base for a 200HP motor and centrifugal pump. I have generally left the concrete/rebar design to others, but I'd like to get more involved in it and understand how to design it. I found the ACI 351.3R Foundations for Dynamic Equipment and ACI 351.2R...

I want to make sure I'm on the right track with MWFRS/C&C concepts. I understand MWFRS are the structural elements that deal with the collected wind loads from C&C. MWFRS loads are generally distributed over larger areas while C&C loads are distributed over smaller areas and are usually higher...
Working on a project on free time to increase understanding of structures.
After applying wind loads I'm getting a deflection of about .600 around the center of the circled column (in weak axis direction). Likely would be where a roll up door would be, but with framing added to support door...
Let's say you have a middle bay braced on the roof (includes roof and side walls). I understand that the roof bracing is designed like a truss and the roof purlins nearest the rod/rafter connection act as the vertical members and the rods act as the diagonal members. I have 2 questions I need...
I was wondering if someone could take a look at these simple calcs and offer advice regarding my approach on weld sizing. I use Blodgett's handbook and use the weld line method and then I use AISC fillet weld capacity and get different answers. I suppose that's due to the way I couple the moment...
Picture of case 2 attached.
Is 2*Rut supposed to be the maximum tensile force value for the tension bolt group? The formulas in 7-14b for just Rut. Just verifying you would need to double that for max...
Evaluating the bolt axial load due to a horizontal pin load causing a moment. I attached my napkin sketch. Is this a reasonable, conservative, approach to approximate...
