Abstract: Seismic energy dissipation systems are typically installed in buildings within diagonal or chevron bracing to improve the seismic performance by reducing drift, and under certain conditions by reducing acceleration. ...

Abstract: Fluidic self-centering devices operate on principles similar to those of fluid viscous dampers, but with additional capabilities to provide recentering force (or preload) and stiffness. The functions of preload, stiffness, ...

Abstract: Seismic isolation bearings consisting of lubricated sliding bearings and steel dampers exhibit nearly elastoplastic behavior. Accordingly, they can transfer force to bridge substructures which is independent of the level ...

Abstract: An analytical study of buildings without and with seismic damping systems was conducted to investigate the dynamic response of secondary systems. The buildings were represented by steel frames designed by the procedures ...

Abstract: Isolation bearings experience tensile forces or uplift under certain conditions during seismic excitation. In general, this phenomenon is undesirable. This paper discusses an uplift prevention mechanism that uses prestress ...

Abstract: Earlier studies found that acceptable probabilities of collapse for seismically isolated buildings could be achieved by an appropriate combination of strength in the superstructure, isolator displacement capacity, and ...

Abstract: The energy dissipated per cycle and the characteristic strength of lead-rubber bearings reduce with increasing number of cycles as a result of heating of the lead core. The reduction is substantial depending on the geometric ...
