Re: Question on independent structurally

[Subject Prev][Subject Next][Thread Prev][Thread Next]
1-  the regular definition for independent structural  mean no any connection to other structural or existing building .
  and shall  deflect free and no connection from the foundations and up to the roof.
2- since  the differential settlement will be no problem  the best solution complete  separate foundations design
the existing building as a property line.

Subject: Question on "independent structurally" w.r.t. foundations

I am seeking a publishd definition in a code, specification, or possibly in design guidelines that defines "structural independent" with respect to foundations.
We need to design a new addition to an existing building that must be "structurally independent" from the existing building.

We know what to do above the foundation. 

What about the foundation?  Must the foundations be physically separate with non-overlapping pressure bulbs?  Or, can the new foundation (say, footings) have rebar doweled into then grouted, and cast against the existing foundation (again, say, footings) *if* the geotechnical engineer doesn't think that differential settlement will be a problem?

Thank you!
