how do you patch a cracked kiln shelf?

Think structurally about the loading when you use it. You likely can stilt the shelf so that the stilt spans the two sides of the crack (or use two stilts close together), then that supports the "intact" portions of the shelf. Load that shelf a bit more lightly than others.
And have a new shelf or two on order.

Think of the shelf as a "spare", and only use it when you run short. There is no real way to fix them, as they just keep cracking.Sometimes shelves crack if they are stacked unevenly, so take a look at your stacking.

With a 3 clay props between each shelve!!!
the props prevent damage to the bottom shelves, should any of the shelves have some unevenness on it's surface, and it also prevents the bottoms of the shelves picking up any alumina that could fall on glaze work in the kiln.
