You are basically just designing a rectangular water tank. AWWA and
others offer guidance on this type of design including sloshing effects,
seismic design, earth pressure, etc. PCA also offers a publication
entitled "Rectangular Concrete Tanks" which might be of help.
Remember that the basin can be empty or full so look at both
conditions. Also, if it is buried, your most important LL may be what is
on top. For example, are there traffic loads which need to be
distributed. AASHTO can provide guidance in this area.
The corrosion issue depends on your expected design life, the
corrosiveness of groundwater and surrounding soil as well as what might be in
the stored water. Although we'd like to think otherwise, no structure is
permanent without careful and continuing maintenance.
In a message dated 9/7/2006 1:59:52 P.M. Pacific Daylight Time,
I'm being asked to
design a detention basin for a civil engineer. the hydrology has
already been done, he just needs structural detailing/design. Having
never done anything like this, i naturally have a few questions that i hope
some of you may be able to answer.
1. I tried
searching for some sort of standard of design, but came up empty
handed. Do any exist? Sources?
2. I assume i'm
just designing a big conrete box to hold water (19' wide x 53' long x 6.5'
deep). So Live Load would be the full volume of water, or can i
consider something less?
3. How about
lateral loads? How do i account for the water sloshing
4. Should this be
constructed w/ corrosive resistant materials?
Any insights, thoughts,
help is appreciated.
