Response of self-centering mass plywood panel shear walls

Abstract

The rocking behavior of self-centering mass plywood panel (MPP) walls was investigated with and without the use of supplementary energy dissipation systems. Two energy dissipation systems were tested. The first system used a kinematically expanding hysteretic damper (KE-HD), whereas the second system used slip friction connections (SFCs). The reviewed energy dissipating systems were used in a self-centering system comprising one unbonded posttensioned (PT) hold-down rod on each side of the MPP walls. The cyclic performance of the PT and the hybrid MPP specimens was investigated through a series of full-scale quasistatic cyclic tests. The test results demonstrated the viability of the investigated energy dissipaters in selfcenteringMPP rocking systems. Results further indicate that hybrid specimens with SFC dissipatemore energy and provide higher strength than those with KE-HDs, however, with higher residual drift.
