Hello All
I was wondering if anyone had a source for empirical calculations of pipe wall thinning due to liquid droplet impingent erosion. Looking for a calculation to predict wear rate of carbon steel piping. I'm working from PVP2012-78443
Potentially Isomoto model?
Any input would be...
ASCE 7-16 states:
11.4.7 Risk-Targeted Maximum Considered Earthquake (MCER) Response Spectrum. Where an MCER response spectrum is required, it shall be determined by multiplying the design response spectrum by 1.5.
My Question:
Recognizing that the design response spectrum is 2/3 the MCER...
Happy Thursday
Can anybody point to a good reference for the detailing/drawing of simple shear tab connections for beams framing into round HSS.
Thank you
Happy Friday
Looking at replacing the entire bottom of a 60' diameter tank. Given the foundation configuration and some other challenges, the recommended solution is to install a second bottom over the existing bottom as specified in API 653 9.10.2. Looking for a couple bench marks from...
Hi
I'm applying a non-uniform hydro-static load in Solidworks Simulation. I know how to create the load and can view it (arrows wise). Does anyone know if theres a way to view the applied pressure as a contour plot on the model, so you can confirm its been correctly applied?
Thanks
Jeff
Has anyone repaired/rehabilitated an AST with a gravel foundation before? Without jacking?
The tank needs a new annular plates anyways so cutting open the floor for access is an option, just thinking about how to get good compaction up to the underside of the tank floor and tight to the shell...
Good afternoon.
I'm looking to add a structural drafting package to my Solidworks Licensee. Can anyone recommend what they're using. I'm running SW 2019. It seems like so many are either unresponsive or no longer supported.
I've found:

I'm evaluating an API-650 tank for external load, snow and external pressure.
The equations (V.7) are
DL + (Lr or S) + 0.4 Pe or DL + Pe + 0.4 (Lr or S)
My tank has a continuous 6" w.c. vacuum applied to it. When looking at the above loading conditions I'm replacing the 0.4 factor with 1.0...
Happy Friday Everyone
I have an intern starting in the office and am looking to teach him FEA. I'd like to teach him some basic FEA that correlates to real world structural analysis and design. I previously had an intern show the effects of bolt prying on wide flange shapes.
Anyway I'm...
Hi Guys
I'm looking for some suggestions on some challenging structural problems you've faced that would've benefited from a Finite Element Analysis.
I'm looking to demonstrate some FEA results against code predicted equations and incorporate into my firm's blog...something that can be...
Greetings all,
I have a project coming up that's a simple bolted/welded steel frame. Typically I'd use weldments to model the whole thing, but the top level BOM always lists everything , beams, baseplates, gussets, etc as separate items.
To accelerate the project, I'd like to split off...
Hi all
I'm using solidworks for top down design (basically using layout sketch to project parts and extrude). I'm being challenged because my parts are jumping from the projection of the layout sketch to random regions. Solidworks says that the part is still confined but i cant figure out...
For fun, what is the most unique engineering unit you've encountered in your years?
Some considerations:
Name
Units that mixing and matching english and metric
Usefulness & practicality
My two first nominations:
KW/foot: A mix & match of english & metric, its used in the commercial nuclear...
Hi all
A recent mentoring session with a new engineer spawned a discussion on the concepts of blast analysis of structures. In our session we discussed concepts of blast loads, single degree of freedom (SDOF) analysis and development of finite element models.
I wrote a blog post to document...
Morning
I have some work that is required to be stamped by an engineer licensed by the Association of Professional Engineers and Geoscientists of Alberta (APEGA). As a non-resident, I need to apply as a licensee.
The APEGA website (www.apega.ca) application portion appears to be down (even...
Hi all
A recent project spawned a water-cooler discussion regarding symmetry theory and FEA. I developed a worked example using ANSYS (LSDYNA) to show underlying symmetry concepts, manual application, and advantages to symmetric analysis.
I think its a great primer, to help new FEA engineers...
Hi all
Had some free time in the office today, and decided to build a finite element model of a preloaded bolted joint subject to external load.
I think its a great primer, and would help new engineers understand load-unload curves of bolted joints as well as Finite Elment Analysis...
Timber Bridge Deck
Greetings all. I'm working on a proposal to develop a timber decked bridge. Essentially the decking timbers lay transversely on top of steel girders which span my structure.
Some material mentions that you can buy pre-fab timber panels (essentially large crane mats) that...
Afternoon All,
Can someone refer me to reading material regarding the design and fabrication of tapered wide flanges.
How are they actually fabricated?
Drawings of typical fabrication details?
Thanks
