Energy Dissipation

Part of the Geotechnical, Geological and Earthquake Engineering book series (GGEE, volume 45)


The chapter introduces the energy balance equation of a generic system. Attention is given to damping energy and plastic energy (Vakakis et al., Nonlinear targeted energy transfer in mechanical and structural systems, vol 156. Springer, Dordrecht, 2008). Two methods are introduced to estimate the damping on the structural systems through experimental techniques: the Logarithmic Decrement Analysis (LDA) and the Half-Power Method (HPM). The ductility factor and the equal displacement criteria is also introduced.
