A critical review of numerically predicted accelerations in nonlinear hysteretic systems

When evaluating the seismic behaviour of a structural system, peak floor accelerations must be considered because they determine the design forces for floor diaphragms and also affect the performance of nonstructural elements. Some studies of new self-centering systems, as well as of base isolation systems, have suggested that structures that include these systems may be subject to relatively large accelerations following abrupt stiffness …
