“…In the latter design, epoxy was commonly used to fill the gap between the steel bar and the steel tube. To avoid the grouting step, in references (Mashal and Palermo 2019;Nikoukalam and Sideris 2021a, b;Liu and Palermo 2020), the inner steel bars were machined with grooves without reducing the diameter of the machined portion as shown in Fig. 7e.…”

Prefabricated construction is attracting increasing interest in recent years, since this construction method has various advantages as compared to the cast-in-situ construction method, such as less construction time, higher quality control and reduced environmental impact. As a typical type of prefabricated structures, precast segmental column (PSC) has been used as the substructure to accelerate the construction speed of bridges. This paper reviews the performances of the PSCs under seismic loadings. In particular, the seismic performances of the PSC itself under cyclic loading and real earthquake ground motions, the seismic behaviours of PSC-supported bridge structures, and the responses of precast rocking column (PRC)-supported bridges, are comprehensively reviewed and their pros and cons are discussed. For the completeness of the paper, the performances of the PSCs under multiple dynamic hazards, namely impact and blast loadings here are also briefly summarized at the end of this paper.

The increasing need to reduce damage and downtime in modern buildings has led to the development of a low-damage design philosophy, where the earthquake loads can be resisted with damage confined to easily replaceable components. Post-tensioned (PT) concrete walls have emerged as a popular lowdamage structural system that have been implemented in a range of buildings. In order to provide essential evidence to support the development of lowdamage concrete structures, a system-level shake-table test was conducted on a two-storey low-damage concrete wall building implementing state-of-art design concepts. The test building included PT rocking walls that provide the primary lateral-load resistance in both directions, a frame that utilized slotted beam connections, and a range of alternative energy dissipation devices that were installed at wall base or/and beam-column joints. The building was subjected to 39 tests with a range of intensity ground motions, incorporating both unidirectional and bidirectional ground motions on the structure with different combinations of wall strength and energy dissipating devices. The building performed exceptionally well during the intense series of tests, confirming the suitability of both the design methods and the connection detailing implemented. The building achieved an immediate occupancy performance objective even when subjected to maximum considered earthquake hazard shaking. The building exhibited only minor damage at the conclusion of testing, with distributed cracking in the floors and cosmetic spalling in the wall toes that did not compromise structural capacity or integrity and could be easily repaired with minimal disruption.The test has provided a rich dataset that is available for further analysis of the building response and validation of design methods and numerical models.
