Depends what you mean by "loaded".  At start of execution, dynamic loader
reads shared object's header files, maps the library to memory accordingly
and probably does some more magic with symbol resolution, etc. (I'm not
an expert and what dynamic loader does is not that trivial).

However, the whole file is not read into memory and instead, needed
portions are read as code references them.
