    Seismic Load for Design Underground Concrete PIT for Water Retaining Structure

    So this is pertaining to Hydrodynamic loads by liquids outside of the pit. How about the liquid inside? Does it contribute any stress together with lateral earth pressure, or are they not applied simultaneously under the same load combination?

    Seismic Load for Design Underground Concrete PIT for Water Retaining Structure

    @r13 do you mean that we can add the hydrodynamic force by the inside liquid from the lateral soil pressure from the outside due to suction?

    Seismic Load for Design Underground Concrete PIT for Water Retaining Structure

    Thanks for your inputs, so in summary we dont apply these loads simultaneously under the same load combination? Im pertaining to hydrodynamic loads induced by liquid inside, the pit by the way.

    Seismic Load for Design Underground Concrete PIT for Water Retaining Structure

    Hi Every one, Doe any one have any input regarding Hydrodynamic considerations for underground concrete pit during seismic activity? Is is an additive from the lateral earth pressure or does it lessen the lateral earth pressure for wall design?
