Hello,
A client is relocating a PEMB canopy about 100 yards from its current location. No change in seismic/wind conditions (SDC D). After reading Ch14 of the 2022 CEBC, our understanding is that since we are not modifying the structure at all (e.g. not adding seismic mass, not removing any structural elements, etc.), we would only be required to design the foundation and anchorage to the current standards. I admit that the language is a bit vague where the 1402.4 exception reads: "Structural elements whose stress is not increased by more than 10%." However, based on other language in the code (ref 503.4), I take this statement to mean that as long as the relocation/modification does not change the D/C ratio by more than 10%, we do not need to evaluate/retrofit.
If the canopy is not receiving any changes at all, then by inspection the D/C ratio is not changing. Therefore we meet the criteria to not perform a full evaluation/retrofit. Is this the correct interpretation of the code?
Thanks for your help.
