Can you replace rafters with trusses to raise ceiling height?
Yes. Talk to your local lumber yard and truss designer. $$$
How can you keep sheetrock from cracking in the winter then moving back together in the summer?
I'm assuming that the "cracks" you are talking about are seasonal. Are they in the corner where the wall meets the ceiling? If so, that is what we call truss lift. This happens when the gypsum board is nailed incorrectly to the truss at the wall intersection and not to blocking on top of the wall. The resolution would be to add blocking on top of the walls between the trusses, do not nail trusses to blocking and do not nail truss down to top of wall plate, screw gypsum to blocking and then remove the fasteners from the trusseswithin 18" of the wall plate. This will allow the truss to move properly with seasonal changes while your ceiling stays put.
What is a ceiling trust?
If the reference is to building/construction, the reader must mean "ceiling truss". If that is the given: ceilings in residential spans (8' to 16') were customarily framed with sawn lumber, 2x6, 2x8, 2x10 and 2x12, depending on whether support for a floor above or no. With the advent of Engineered Lumber (in the mid fifties), longer spans with flatter ceilings could be achieved. Starting with Sanford Truss and Gang-Nail Systems (the first patents), wood webbed, metal gusseted trusses were used as ceiling members, eliminating intermediate bearing (span exterior wall-to-exterior wall) with no sacrifice in integrity. Later, (mid 60's) Troutner patented the Trus Joist (not really a truss (an open web member) but more than a joist). The Trus Joist had the strength of a truss, stiffness needed for long spans and the straightness desirable for flat ceilings (a truss needed to have camber). The camber was difficult to control and caused concavity.
