SYMBOLS
ρ = Redundancy factor
QE = Redundancy factor
Redundancy is an important property for structures designed with the expectation that damage will occur. Redundant structures have alternative load paths so that if some elements are severely damaged and lose load carrying capacity, other elements will be able to continue to provide a safe load path. Adequate redundancy is ensured when a large number of plastic hinges must form throughout the structure in a progressive manner before formation of a mechanism and when no element is required to provide the full seismic resistance of the structure. Redundancy factor, ρ, is automatically obtained horizontal seismic forces according to ASCE 7-16 Section 12.3.4.
