Structural System progress print

Below is my first pass at a framing plan for the upper levels(see brief narrative below the sketch). The odd shaped pieces are rigid box frames within the containers which can be attached to the core building frame. As you can tell, I am definitely NOT a structural engineer, so I will take any advice I can get....

In terms of a structural system, I intend to have a steel frame on piles for the core building, exhibit space, and classroom space. Floors will be concrete on metal decking. Roof will be membrane on rigid insulation on metal decking for the core building and green roof at classroom. Walls will be precast concrete panels attached to the steel frame for the core building, insulated metal panel for the classroom, and translucent insulated glazing panels for the exhibit space.

As you can see above, the trickiest part of the structural system will be tying the prefab container units into the core building's frame. Is the core building one complete system that the container merely plugs into, or are there two separate systems, one for the core and one for the containers, that are attached together in the field? Sketches to follow
