Experimental study of a self-centering prestressed concrete frame subassembly

Experimental study on a precast beam-column joint with double grouted splice sleeves

“…However, the use of energy dissipation devices is needed to enhance the ability of prefabricated beam to column joints using post-tensioning to dissipate energy due to their low inherent damping [28]. Although different types of energy dissipation damping devices including steel yielding devices [22,29], friction damping devices [30][31][32] and lead extrusion damping devices [33,34] have been experimentally validated through beam-column connection tests. For these joints using prestressing technology, the cost is considerably higher than a comparable cast-in-situ concrete structure [35] and the construction procedure of the precast prestressed connections is very complex [4].…”

Parametric Study on Self-centering Precast Concrete Frames with Hysteretic Dampers

“…Morgen and Kurama [6] tested large-scale beam-column specimens under reversed cyclic loading with and without novel friction dampers, and the results showed that the dampers can be designed to provide a significant amount of supplemental energy dissipation to a frame, while the self-centering capability of the structure is preserved. Song et al [7] and Guo et al [8][9][10] experimentally studied the behavior of a self-centering moment resisting concrete frame with beam web friction devices under cyclic loading, and the energy dissipation capability of the self-centering frame system was directly influenced by the magnitude of the friction bolt forces. With the continuous research on the self-centering precast concrete frame structure, its energy dissipation performance has been significantly improved.…”

A conceptual study of a self-centering semi-rigid connection with energy dissipation for wooden frames

“…This has encouraged the development of seismic protection technologies that have demonstrated their effectiveness in protecting structures to avoid a collapse in large seismic events and reducing damage during recurrent seismic events of less intensity (Rai et al, 2009;Ronca et al, 2014) Self-centering connections with energy dissipation are among the most analytically and experimentally investigated systems in the last decade (Wolski, Ricles & Sause, 2009;Smith et al, 2012;Padilla-Reyes et al, 2018). These connections are used in different structural systems, such as rigid frames (Garlock & Jie, 2008), braced frames (Roke et al, 2009), and hybrid coupled (Zareian, Esdahani & Hosseini, 2020), as well as in different parts of a steel structure (Zhang et al, 2019), reinforced concrete (Song et al, 2015) and wood (Palermo et al, 2012), with the aim of reducing the deformation of structural elements.…”
