“…Sub-step 1: Determine the core plate energy dissipation segment cross-section area A cp . A cp is determined primarily based on the design objective of concentrating damage on the core plate, as shown in Equation (3). where η is material strength modification factor, it is 0.29 (0.3 × 332/341 = 0.29) when the damage is designed to concentrate at core plates, and 0.49 (0.5 × 332/341 = 0.49) when the damage is allowed to exist in panel zone.…”

“…The time and economic cost of repairing such structures are low after an earthquake. Currently, seismic resilient structures consist of three main types: self‐centering structures, 1 rocking structures, 2 and structures with additional replaceable energy dissipation components 3,4 . The replaceable energy dissipation components are also frequently used in self‐centering structures and rocking structures to improve the energy dissipation capacity of structures.…”

“…Various forms of replaceable energy dissipation components have been proposed and intensively studied. [3][4][5][6][7][8][9][10] Typical additional replaceable energy dissipation components in beam-to-column joints include friction dampers 5-7 and metal dampers. [8][9][10] These replaceable energy dissipation components in beam-to-column joints are more important for achieving seismic resilience of steel frames under earthquakes.…”

A replaceable buckling‐restrained flange cover plate (BRFCP) was previously proposed to improve seismic performance of beam‐to‐column joints. Quasi‐static tests were conducted to investigate the seismic performance of beam‐to‐column joints using three different formats of restraint plates for BRFCP: no restraint plate, separated restraint plate, and integral restraint plate. The test results showed that both separated and integral restraint plates restrained the core plate buckling under compression and increased the beam‐to‐column joints load resistances. This paper first validates finite element models (FEMs) using test results. Then the validated FEMs are used to investigate influences from different BRFCP design parameters (such as core plate thickness, restraint plate thickness and length, restraining gap size, and restraint plate blot prestress force) to the beam‐to‐column joint load–drift hysteretic responses. Finally, the paper proposes a design range of each investigated design parameter and a BRFCP design procedure.

“…Later, due to the fracture in the angle steel damper, the energy dissipation capacity of the pier is reduced, and the concrete pier body is basically free of damage. Sun Zhiguo [13] et al proposed a swing self-centering prefabricated assembled double-column pier with angle steel and energy dissipation reinforcement, and analyzed its seismic response under a near-fault earthquake based on the OpenSees numerical platform. The results show that the developed swing self-centering prefabricated assembled double-column pier has good seismic capacity and small residual displacement after an earthquake.…”

In order to develop a new type of prefabricated bridge structure system with green, efficient and recoverable function, which complies with the new requirements of rapid repair of pier function after earthquake, and improves the applicable performance of prefabricated assembled pier in medium and high-intensity seismic areas, a precast segmental concrete-filled steel tubular (PSCFST) pier with an external energy dissipation ring is proposed. Based on ABAQUS analysis software, a four-segment PSCFST pier model is established, and the pseudo-static comparative analysis is carried out between the traditional PSCFST pier and the PSCFST pier with the external energy dissipation ring. The results show that compared with the traditional PSCFST pier, the lateral bearing capacity of the PSCFST pier with an external energy dissipation ring is increased by 60%, the energy dissipation capacity is increased by about 20 times, and the damage is concentrated in the energy dissipation ring, the damage is controllable, and the rapid repair after the earthquake can be realized by replacing energy dissipation devices and other measures. At the same time, the seismic performance of pier models with three different control parameters (initial prestress, material strength of energy dissipation ring and section width of energy dissipation ring) under reciprocating loading is analyzed. The results show that the initial prestress does not affect the cumulative energy consumption of the pier; the increase in the material strength of the energy dissipation ring improves the overall stiffness and improves the energy dissipation capacity of the PSCFST pier; the reduction in section width will affect the overall equivalent stiffness and unloading stiffness of the segmental pier, and the energy dissipation capacity will be significantly reduced.
