摘要

The reliable evaluation of inelastic deformations seems to be decisive for the seismic design of structures, especially for displacement-based-design methods. Inelastic Displacement Ratios (IDRs), Inelastic Velocity Ratios (IVRs) and Inelastic Acceleration Ratios (IARs) allow the computation of maximum inelastic displacements, velocities and accelerations, respectively, directly from the corresponding elastic ones, avoiding the execution of complex inelastic analyses. The evaluation of IVRs for inelastic structures subjected to strong earthquakes has received little attention, in comparison with the computation of IDRs, while that one of IARs seems that has not yet been examined. This work examines the whole set of inelastic ratios, i.e., IDRs, IVRs and IARs, for systems subjected to pulse-like ground motions.
