Building effect in psuedostatic analysis
Building effect in psuedostatic analysis
(OP)
There is a building basement in the back of a slope. The basement penetrates the whole height of the slope. I believe there is some effect on the slope stability from the building inertia. But in limit equilibrium analysis, the software cannot consider the inertia coming out of sliding body. If I apply the inertia manually, how to calculate the inertia force induced by the building? Thanks.

Now consider the base shear acting on the basement and the isolated column footings (if any). There will be some resitance to the unbalanced earth pressure from these reactions.
Whatever's left over would contribute to slope forces. I'd bet their trivial.

The foundation pressure is 7.5ksf and the foundation depth is 40 ft. The building is actually much heavier than the soils. That's the reason I want to check the building inertia effect on the fill slope. I don't think the slip surface under soil gravity and inertia can reach the basement, however with consideration of building inertia I am not sure. And also the building's acceleration may higher than soils.
Thanks.
