Abstract
The present disclosure relates to stair systems and methods for allowing stair movement, including rotational movement, between building levels while maintaining the structural integrity of the stair system for safe egress passage and ingress passage. The systems and methods of the present disclosure allow for independent movement of the surrounding building walls, landings, floor slabs, and/or any other portion of the surrounding building structure or stair system. Embodiments of the present disclosure are suitable for use in both new constructions as well as in existing constructions for retrofit applications to allow for movement between levels, landings, or within stairwell structures. The present disclosure can reduce stair damage during building movement whether it is from wind, thermal, explosive, or seismic activity, and/or any other type of suitable force or experience, as the present disclosure allows for rotational movement, longitudinal movement, or a combination thereof.
