masonry containment/tank
masonry containment/tank
(OP)
Hi
I have project where I have containment structure for a tank, which will have to hold liquid in case of spilling. I'm using masonry blocks. Wall is only 4ft tall, liquid level 2ft. structure is rectangular 31'x31'.
Can I apply design methods from ACI 350 and just use values for masonry?

Am I missing something here?

thanks

Think about this, are you sure the wall will remain functioning and serve its purpose? Before checking, there is no straight answer.
Please talk to your boss or seniors to setup design criteria, and determine proper code for the design and check.
Good luck.

I guess my main question was if I can use ACI350 to calculate inertia force and convective force, since this is only code that I found that has equations for rectangular, open top tanks. I would assume that if spill occur my containment wall acts like open top rectangular tank.
I would take this with my senior but currently he is on thanksgiving vacation

Check IBC on how to apply and make load combinations, then check stresses/strength use the code specifically developed for the material in use.
I agree, it would be a rare event that the wall will experience both spill and earthquake at the same time, but I wouldn't ignore it completely.
As suggested by LRLORD, concrete wall sounds a better choice.

I was going to design the wall for forces due to the earthquake any way. thanks

I agree that ACI350 is for concrete not masonry. But ACI350 is the only code that has equation to calculate seismic forces for rectangular, open top tanks due to liquid movement. That was the point of my question.
After calculating seismic forces I will use ACI530 to design masonry wall, or ACI350 if client goes with concrete wall.

and now that I'm looking closer the code is ACI350.3 it is for computing seismic forces only, and it is companion document to chapter 21 of ACI350.
