Abstract
A stair system with freedom of movement between landings associated therewith includes a connection system configured to connect stairs to a landing associated with a construction, wherein the connection system structurally supports the stairs for safe egress over the stairs while concurrently supporting movement between the landing and a second landing associated with the construction by the stairs in at least one dimension, and wherein the movement supports inter-story drift between the landing and the second landing and removes some force translation between the landing and the second landing.
