Abstract Structural components may enter an initial-elastic state, a plastic-hardening state
and a residual-elastic state during strong seismic excitations. In the residual-elastic state,
structural components keep in an unloading/reloading stage that is dominated by a tangent
stiffness, thus structural components remain residual deformations but behave in an elastic
manner. It has a great potential to make model order reduction for such structural
components using the tangent-stiffness-based vibration modes as a reduced order basis. In this
paper, an adaptive substructure-based model order reduction method is developed to perform
nonlinear seismic analysis for structures that have a priori unknown damage distribution. This
method… More >
