RE: Concrete tank's vertical reinforcement

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I would suspect that the control of cracking, in this case flexure or/and
direct tension cracking in mature concrete and  direct tension in immature
concrete might govern the use of reinforcement in both directions.

Subject: Concrete tank's vertical reinforcement


Does any one has any info on design of circular reinforced concrete tank?
As we know, the horizantal reinforcement is determined by hoop tension 
reslted from radial pressure of water.
But What I'd like to verify is the force that determines the bending moment 
and therefore vertical reinforcement in the wall.
I'd take the lateral  pressure of the water-adjusted for seismic slush- and 
use that to determine the max bending moment in the wall.
Your input is greatly appreciated.
