Hello,
While designing any pipe rack / process structure, wherein piping loads play a significant role, do those piping thermal loads (guide / anchor in specific ~ thermal component of course ... which are normally treated as Dead Load)are ADDITIVE with amplified seismic loads?
In particular the...
@nutte:= You've correctly interpreted what I'm actually looking for and thanks for sharing the definitive info.

@CANPRO: I'm working with this fabricator for the first time, already flashed red-card to them as they don't posses at the least the foggiest...
@ CANPRO:
Even though you're welcome in expressing your opinion - however just for your information the above referenced AISC design guide stands for either the HSS or the vertical brace I believe.
Moreover, if you think of stretching this issue unnecessarily - I beg to differ - circumstantially...
All,
Thanks for your response.
Yes have all the requisite forces are mentioned on the drawings/connection force's table, however Fabricator had missed (?) the inclusion of axial force into the connection design for the subjected connection. Of-course I could reject the shop drawings even I am...
CANPRO,
Thanks for your prompt response.
In particular, I'm involved in a project wherein connection design resides in Fabricator's scope... only I need to furnish the appropriate member end forces.
There are few cases wherein axial loads are significant, would dictate alternative connection...
Hey All,
Could you please throw some light onto the design principles of a single plate shear connection, often referred to a shear tabs - when axial force is travelling through beam ends.
I am working in a project wherein connection design falls into Fabricator's scope - my job is to furnish...
It is common knowledge that maximum practical fillet weld size is ½” (13mm) – common practice to employ another type of weld, such as groove weld, when the calculated weld is greater than ½”(13 mm).
Typically CJP welds are the most expensive weld and I feel the same should be reserved for...
Friends,
Greetings.
Need your advice.
Topic - Design of gusseted/stiffened base plate in consonance with LRFD design principles
Question: Could anyone apply Roark's formula while using factored level forces for base plate design?
Since one of the chief assumption of Roark's formulas is...
@ Ingenuity :=
Thanks for the prompt response.
You are absolutely correct I am concerned only with under-hung/under-running monorail hoist without any orthogonal runway beams. Me too have come across a similar literature that suggests consideration of lateral force as high as 20% - also...
Hello Everyone,
I have one question as to the applicability/feasibility of lateral forces (?) on the bottom-running monorails systems - travelling along the bottom flange of the supporting beam.
Understandably, in case of top running crane girders lateral surge force is mainly derivative of...
Is your column a regular wide flange shape column or a different one viz. cruciform column etc...?
You may please refer to the wide variety of suggested base plates appropriate for the mentioned range of heavy loading available in the Book titled "Design Of Welded Structures by Omer W...
Thanks everyone for their reply -
Specifically I am looking for the following info -
a. Should the end post be designed for crane girder end reaction alone similar to an end baring stiffener? Or else I need to consider something more on it.
b. What's the design philosophy regarding the...
Hello Everyone,
Greetings.
I am new to this community. At the very first want to thank this forum and members for their able contribution in advance.
Could anyone please let me know what's the best suited connection details between crane cap and crane leg?
My column configuration is as...
