Abstract

The initial studies reported involve investigation of simple elastoplastic structures when subjected to various pulse-types of ground excitation, including actual earthquake ground motions. Among the results documented are structural deformation response, input and hysteretic energies, and numbers of yield excursions. Also included are the results of a limited Fast Fourier Transform study and the observations arising from an experimental investigation of a simple structure. The second set of studies reported involve the development of two comprehensive seismic damage evaluation criteria. One criterion converts the dissipated hysteretic energy into an equivalent number of identical hysteretic cycles employing three different cycle definitions. The second damage criterion accounts for the accumulation of structural damage caused by random inelastic cyclic response through hysteretic plastic ductility and damage index parameters founded on low-cycle fatigue concepts. Comparison against existing experimental data show the criteria depict damage well. Three applications of the damage criteria are presented, and possible applications to current design philosophy are presented.
