Can anyone give me
some references for seismic design of retaining structures?
I'll try to explain
the situation I have.
I have a concrete
building partially below grade. The inside clear height is approx.
20' +/-, the walls will be cast in place retaining wall, retain about 17' +/- of
soil on three sides of the building. The roof will be pre-cast planks with
topping slab. The building is about 100' x 100'. The concrete
topping slab will be the rigid diaphragm on the roof. How would the
seismic load from retained soil be appliced to the diaphragm, since there will
be equal amount of retaining at the opposite sides of the building. If the
retained soil is in contact with the retaining wall at all time, then there
won't be much of diaphragm force, only thing left is the axial
compression left in the planks.
