1. A stud rail system for a reinforced concrete structure defining a column portion and a slab portion, the stud rail system comprising:
at least one stud rail assembly comprising
a plurality of rail portions,
a plurality of cross portions, where a plurality of sets of support openings are formed in each of the plurality of the cross portions,
a plurality of pin projections, where each rail portion supports at least one pin projection,
a plurality of support assemblies, and
a plurality of support projections, where each support projection is supported by one of the plurality of support assemblies; wherein
each of the support projections extends through one of the support openings in each set of support openings such that the rail portions are rotatably connected to cross portions at a plurality of axis points to allow the stud rail assembly to be reconfigured between a collapsed configuration and an expanded configuration;
before and during pouring of concrete to form the slab portion, the at least one stud rail assembly is arranged at a desired location and orientation relative to the column portion; and
when supported at the desired location and orientation during pouring of the concrete slab portion, the at least one stud rail assembly is arranged within the slab portion such that at least the cross portions, the pin projections, the support projections, and the support openings of each stud rail assembly are outside an area above the column portion.
