“…Research and development of precast concrete jointed and rocking structures has gained considerable momentum over the past two decades, with significant research on the so-called PRESSS 3 systems [1], damage-avoidance design (DAD) [2][3][4] in the Unites States and New Zealand [5][6][7]. These systems, designed to accommodate inelastic behaviour by rocking at specially detailed 5 joints, have proven to provide a level of seismic resistance comparable to current standards while remaining almost (in the case of PRESSS) or essentially (in the case of DAD) damage-free.…”

9SUMMARY Ductile-jointed connections, which generally require some form of supplementary energy dissipation to 11 alleviate displacement response, typically employ mild steel energy dissipation devices. These devices run the risk of low-cycle fatigue, are effective only for peak cycles that exceed prior displacements, are prone 13 to buckling, and may require replacement following an earthquake. This study presents an experimental investigation employing an alternative to mild steel: a high force-to-volume (HF2V) class of damper-based 15 energy dissipation devices. Tests are performed on a near full-scale beam-column joint subassembly utilizing externally mounted compact HF2V devices. Two configurations are considered: an exterior joint 17 with two seismic beams and one gravity beam framing into a central column, and a corner joint with only one seismic beam and one gravity beam framing into a column. Quasi-static tests are performed to 19 column drifts up to 4%. The experiments validate the efficacy of the HF2V device concept, demonstrating good hysteretic energy dissipation, and minimal residual device force, allowing ready re-centring of the 21 joint. The devices dissipate energy consistently on every cycle without the deterioration observed in the yielding steel bar type of devices. The effectiveness of the HF2V devices on structural hysteretic behavior 23 is noted to be sensitive to the relative stiffness of the anchoring elements, indicating that better efficiency would be obtained in an embedded design.

“…The maximum suffered concrete compressive strains of the PPCW buildings are in the base-to-foundation section, which are presented in Figure 14. Unlike cast-in-place shear walls, damage to PPCWs is often featured by crushing of confined core concrete at the wall toes [3][4][5]16]. As expected, the maximum concrete compressive strains are found around the wall toes, and the observed concrete compressive strains are lower than design ultimate concrete compressive strains (0.02 for confined concrete; 0.004 for unconfined concrete).…”

“…The adoption of PT tendons allows the precast wall panels to open at the base and also minimizes the residual drift by providing a restoring force, resulting in a flag shaped hysteresis loop. A series of experimental and analytical studies conducted on the unbonded PPCWs have demonstrated the excellent seismic performance of PPCW structures [3][4][5][6][7]. Wiebe et al [8] investigated the seismic performance of multiple rocking sections over the height of one single shear wall models.…”

“…Research and development of jointed precast concrete structures has gained considerable momentum, with significant research on the PRESSS systems (Stanton et al, 1997;Priestley et al, 1999) and Damage Avoidance Design (DAD) systems (Mander and Cheng, 1997;Holden et al, 2003;and Ajrab et al, 2004). These systems accommodate inelastic behaviour by rocking at specially detailed joints, and provide a level of seismic resistance comparable to current standards for ductile (damage-prone) structures, and remain essentially damage-free, without the excessive residual displacement, common in conventional systems.…”

An experimental and computational study of an 80 percent scale precast concrete 3D beamcolumn joint subassembly designed with high force-to-volume (HF2V) dampers and damage-protected rocking connections is presented. A prestress system is implemented using high-alloy high-strength unbonded thread-bars through the beams and columns. The thread-bars are post-tensioned and supplemental energy dissipation is provided by internally mounted lead-extrusion (LE) dampers. A multi-level seismic performance assessment (MSPA) is conducted considering three performance objectives related to occupant protection and collapse prevention. First, bi-directional quasi-static cyclic tests characterise the specimen's performance. Results are used in a 3D nonlinear incremental dynamic analysis (IDA), to select critical earthquakes for further bi-directional experimental tests. Thus, quasi-earthquake displacement tests are performed using the computationally predicted seismic demands corresponding to these ground motions. Resulting damage to the specimen is negligible, and the specimen satisfies all performance objectives related to serviceability, life-safety, and collapse prevention.
