Abstract:

Nonlinear Kelvin and Maxwell impedances connect lumped masses to form arbitrary networks. Viscoelastomer-steel composite moment connections are modeled similarly, using auxiliary masses, to form composite impedances for inclusion into the model. The general solution is presented and illustrated by comparing simulated base and floor isolation responses of a building.
