Balanced linear-friction dissipator placement for truss structures

The linearized model and the energy balancing techniques are used in this paper to design the best placement of dissipators for truss structure. The ratio of future output energy to pass control-input energy under balanced modal realization of truss structure is chosen as the placement index. This balanced modal state-space representation is almost invariant under small damping condition. Numerical examples with various configurations with different dissipator placements are designed based on the placement index and show satisfactory results
