a new 44m long concrete building with expansion joint to be put vertically in the middle of the building ,
is it ok to make the joint in the walls , columns and slab, but keep the foundations connected

RE: expansion joint
Exp. joint in foundation is achievable, but not advisable (see Mike's comment above for reason 1). Even worse, I can see the concrete wall being rigidly connected to the foundation system, when it decides to take a walk (move) but is dragged (restrict) by the foundation monolith, now what, how we settle this conflict?
RE: expansion joint
I wonder why you need a movement joint in a building only 44m long. Unless there is some major discontinuity in the type of building, I would build it as one.
