Performance of baseplate energy dissipating mechanisms in rocking cold-formed steel storage racking
Cold-formed steel storage racking is used for bulk storage of products which are often much heavier than the structure itself. The combination of high loads and light structural members can make the racks susceptible to collapse during earthquake motion. To increase the resilience of such structures to cross-aisle ground motion, two novel types of energy dissipating baseplates were tested: 1. Unanchored baseplates that allow the structure to rock; and 2. Friction sliding baseplates that allow rocking while dissipating energy through friction.
