Expansion / isolation joints in precast framed building?

Expansion / isolation joints in precast framed building?

Expansion / isolation joints in precast framed building?

(OP)
Hello all,

I am currently designing a very large (190m x 190m) retail store in the Middle East for a well known furniture company. It is a 2 storey building with a single level basement, relatively square on plan. The client has very specific construction guidelines they want adopted for all of their stores - precast concrete framing (beams and columns) with hollow core slabs. They are also very averse to joints in the building, preferring not to have any at all!
With the precast concrete I don't think shrinkage movement is a concern as the majority will have occurred prior to erection. Regarding thermal movement however. The ground floor (parking) is mostly open and not temperature controlled, therefore do I need to provide a movement joint through the superstructure? obviously the insitu basement slab and retaining walls will have joints (late pour strips for the walls) but I would prefer not to have any joints through the super structure though as it will complicate my stability system having separate strucures....

can anyone offer any advice on this?

Thanks

Tell the client buildings behave differently from furniture.

190m on a open carpark is a very long way.

...and that middle eastern deserts go from very hot in the daytime to very cold that very same night...not like, say, a snow covered Nordic country where temperatures presumably don't fluctuate that dramatically in the course of one day.wink

I would also tell the client that I trust the furniture will not fall through the cracks.
