Alright everyone thanks for the input. I appreciate it. I got focused on a solving the problem one way and made it more complicated than it needed to be. I just needed someone to help shake me out of my train of thought.
The load path isn't as bad is it might seam, there are some unavoidable eccentricities that I am dealing with. I'll make it work. The member going to the top right is mostly for stability and doesn't carry a lot a load. Overall this is a fairly lightly loaded structure.
Here is an update...
Sorry , I should have provided a better image. here is an Iso I have hopefully that illustrates it better. its a splice, so connection is more or less mirror with another angle end plate connection The yellow highlighted angle is what connects into the yellow highlighted end plate. The gusset...
We are looking into doing an angle end plate splice. It feels unconventional to me, but I can't think of a logical reason why it wouldn't work so I am moving forward with it. The problem is that I can not think of a way to design all of it. Gusset/stiffener plate will be added to the angle to...
Yeah the challenge is that I wouldn't be using stainless materials that are too out of the ordinary. I am talking 304 or 316 stainless, in duplex it would 2205. My suppliers insist that it is only available in 4' width. I've looked at some online suppliers and they all only list 4' wide plates...
I'm looking through the design on stainless tank API 650 tanks, and I have a few practical questions for you all.
1. How do you all deal with the requirement for stainless steel course widths being set to 4' (without approval) when the only plate widths available in stainless are 4'. Unless...
There is some discussion in the office on what is the "right way" to locate a nozzle in terms of degrees on the the circumference. What we have found so far is in API 650 starting that north should be 0 degrees and north should be upwards per in L3.2.3, but there doesn't seem to be any mention...
I know my question is messy. I sure I am over thinking this and that obvious by my question.
You basically described exactly how I figured it says me to do it. AISC method includes provisions using allowable stress so it shouldn't be a problem.
I think the reason I am so confused by because of...
I'm asking a question I've came across in the past, but haven't had to deal with until recently.
Per AWWA D100-21 13.3.3.2 it says to include P-delta effects for a lateral drift equal to three times the elastic deflection. ASCE 7 has something similar. Correct me if I am wrong here, but they are...
We are using API 620. I was looking for anything in any code so I could reference it for my best judgement.
We can't move the nozzle. The columns can be moved to some extent, but not enough to solve the issue.
I haven't looked into different reinforcement configurations, admittedly I've just...
We have a cone bottom elevated tank with a nozzle placed super close to the column extensions up the tank walls. API 620 5.14.5 requires the nozzle reinforcement to be 6 in from the nozzle reinforcement, which in this case is just simply not possible. However the note to that section says that...
Is there somewhere in any of the code books (API 650/620 AWWA D100) that addresses using a different shell plate for adjacent plates in the same course? I seems to remember reading about it, but I can't remember if its addressed in a code book and I cannot seem to find it.
For for my own understand let me rephrase your suggestion in my own words.
Do you suggest that I model the wind drift by stacking a series of round columns on top of each other set to the diameter of the tank, each column representing the thickness of their course. Then I use that to determine...
I am having a hard time understanding the results of some seismic calcs following API 650. I've asked around in my own sphere of my world through the years and no one has ever had an answer I've found satisfying, so I thought I'd throw this out into the universe and see what kind of response I...
Any ideas on how to find wind drift on tank analytically without the use of an FEA? I have searched through API 650, API 620, and AWWA D100. I'm pretty sure its not in there. I've been doing tanks for a while, but you never know maybe I've missed it. I'm ready to break out ASME VIII, but I...
