    Abstract

    Self-centering systems, such as base-rocking-wall systems, have been studied and demonstrated to be capable of achieving enhanced seismic-resisting performance. For these rocking-wall systems, unbonded post-tensioning strands and damage-permitted energy-dissipating fuses are usually implemented along the full height of the walls. Structural damage and residual deformation of main structures can be mitigated through deformation of the fuses which are replaceable after strong earthquakes. An innovative self-centering system referred to as a pendulum-type nontraditional tuned mass damper system is newly proposed in this paper, which can be deemed to be an inverted rocking system. Pendulum components can automatically return to their original position due to the effect of gravity, without any post-tensioning strands being required. Energy dissipators are only implemented between the bottom end of the pendulum component and the ground, and they can be easily fabricated and replaced. Both experimental and numerical studies have been carried out to examine seismic performance of the pendulum-type nontraditional tuned mass damper system, and it is found that satisfactory control of interstory drift and floor absolute acceleration can be achieved, while small movement space is required.
