soil structure interaction
soil structure interaction
(OP)
can someone help me with understanding this statement please.
a structure should be designed to be flexible as possible and as stiff as necessary in relation to the design of structures and foundations?

RE: soil structure interaction
The more flexible the structure the less lateral load that will need to be resisted by the foundation. The more stiff a structure the more lateral demand on the foudnation.
For example a pinned portal frame that resist lateral load primarily through the column connections with the beam will not transmit lateral load to the foundation. A fixed based frame will thus requiring special consideration of the soil-structure interaction. Of course there are many different foudnation methods that can readily handle the fixed base foundation but the point is, I think, is that deep foundations are expensive and not always necessary.
I hope this helps.

RE: soil structure interaction
You could also just be talking flexibility to handle differential settlements, but stiff enough not to cause damage to the structure, foundations, and the finish work attached to them.
RE: soil structure interaction
Qshake, not sure i understand what you are getting at. All the load is ultimately transferred to the foundation no matter what the structure. How it is transfers varies but it still has to go there.
