Sir HTURKAK,
Thank you for your response. I really appreciate it. I will read those sections/annex you referred.
Wind velocity is 290kph. Yes sir.
The tank content is water Sir.
Sir lFRs,
It's ok, I understand. I'm just feel nervous when the time I found out that my tank design is still not ok. Since there's alot of design criteria I have to consider. Lack of design criteria is my problem from the very start, I know it.
I tried to tell this to my boss before, but it...
What about the operational and design pressure of full of water. How can I use that?
When I calculate the shell thickness, I only used the formula and the height from the top of tank shell. For example in 2nd photo, I calculate the 1st or bottom course with a height of 17.00m.
And for the...
Sir lFRs
I didn't used section 5.9 for wind girders. When I noticed that Annex V has more detailed about buckling, specially it has detailed example calculation.
I should design the tank/s for both section 5.9 and Annex V?
Sir lFRs
Therefore, I should told this to my boss? The he need to contact/email the client and request for the values specially for (internal pressure, external pressure, and seismic parametets).
I already know the location. That is why I calculate the wind load and some seismic paramters...
Sir HTURKAK
i. The calculation of internal pressure you are talking about is can be found at API 650 Annex F? If not, can you give me reference.
Using external pressure of 6.9kPa (maximum for API 650 - Annex V) is ok or I'm safe with that? Since I can't find the section or annex in API 650...
Thank you Sir IFRs, what about roof framing? How do you design roof framing like that?
In my case, I used STAAD.Pro and check it manually. My boss always suggest that if the structure can be designed using software, then use software.
My boss told me that it should be anchored. Maybe because it has slopped bottom.
Now you can see. API 650 doesn't have section or provision about agitator and slopped bottom.
Any ideas and suggestions are really appreciated.
Thank you.
This is a rafters for dome. But this is for reference only. I'm design for cone roof.
As you can see, there vertical I section outside the tank shell.
I already design roof framing for steel tank and it is locate inside the tank.
But now, it is stainless steel tank. The client wants the roof...
This is 1 example of the tank, stainless steel. As you can see, no vent.
The agitator weight is 5tons.
Sir HTURKAK, these are the datas you are looking for.
Sir IFRs, yes. I will add vertical beam outside the tank shell.
That's the problem, no info for agitator motor to be use.
For example, I already know the agitator torque. Is there any other formula to be consider. Or a fomula with relation between tank/shell and the agitator torque?
If mild...
I'm waiting until the pandemic is gone, and look for another company.
I'm aware that these should be design with someone with experience.
Again, maybe this is so rude but I don't have a choice. My intention is to over design and over price the tank/s.
Over design for my safety and over price...
Mr. MJCronin, concrete and steel frame. How about you, are you going to do that? Because I won't. If you don't know something just study and get some advice with person/s have experience on it. I thought anyone can ask some professionals here?
I'm just asking some advice, I'm not asking you...
Based on your replies Sir HTURKAK and Sir MJCronin. There's alot be consider when designing of tank. Yes, I agree. To be honest, my boss give me an old design of tank. It is already operating since 2008. The design is very simple. The pass designer used 1 foot method only, and that's it. A very...
Sir MJCronin, I'm a civil engineer. With less than 1yr experience. My specialty is analysis and design of steel frame, concrete frame, etc. but not for tanks. Tanks are special structure. I'm struggling because I don't have senior to ask. In our department, we have electrical and mechanical...
