“…ereafter, new types of PT connections with bolted ED angles were investigated analytically and experimentally [7,8]. Some of the experimental results validated that the columns and beams remained elastic, while plastic strain occurred on the angles to consume energy under a relatively large drift.…”

This paper introduces a review of self-centering steel frame systems for seismic-resistant structures. The components and basic mechanisms of the developing posttensioned connections and self-centering braces are briefly introduced. The structural details and seismic behaviors of the self-centering systems proposed in recent years, including connections, energy dissipating braces, and steel frames, are condensed in categories. The theoretical and experimental results indicated that self-centering action could minimize residual deformation and structural damage. The energy dissipating capability of the self-centering systems is greatly enhanced by the application of energy dissipating device. The shape memory alloys (SMAs) and prepressed springs which exhibited great potential in energy dissipation and recentering capability have been studied increasingly in recent years. Abundant numerical models were propounded to investigate the cyclic response of these self-centering systems. The current research challenges and the critical issues which need further study are discussed at the end of this paper.

“…Based on this study, some other energy dissipation components were employed in this connection, e.g. friction dampers and small steel braces (Christopoulos et al , ; Garlock and Li, ; Kim and Christopoulos, ; Chou and Lai, ; Kim and Christopoulos, ; Deng et al , ). The test results showed that these energy dissipation components presented satisfactory performance under cyclic loading.…”

Traditional self-centering coupling beams display a beam elongation effect under large shear deformation. The beam elongation effect conflicts with the rigid slab assumption and may induce harmful compressive stress between the coupling beam and the walls. This paper proposes a novel self-centering coupling beam, aimed at eliminating the beam elongation effect. The proposed self-centering coupling beam consists of two connecting parts and one central rocking part. The main feature of the self-centering coupling beam is the gap between the central rocking part and the one connecting part. This gap provides sufficient space for the beam elongation effect. Friction dampers are installed at the corners of the coupling beam to provide energy dissipation capacity. An experimental study, including three specimens, was carried out. The test results demonstrate the satisfactory self-centering and energy dissipation capacities of the novel coupling beam. Based on these test results, we quantitatively discuss the pretension force in the pretensioning strands, the friction force of the damper and the gap width in the coupling beam. A finite element analysis is performed, showing that the coupling beam gap protects the coupling beam and adjacent shear wall from damage caused by the beam elongation effect.Note that the maximum strength of a 15.2-mm PT strand is almost 260 kN, and the reserved width of the gap is 30 mm. According to Equations (4) and (6), the corresponding upper limits for the shear SELF-CENTERING COUPLING BEAM ELIMINATING THE BEAM ELONGATION EFFECT

“…Prestressed steel strands can effectively provide a self-centering capacity for beam-column joints and improve the energy dissipation capacity, without serious structural damage [22][23][24][25][26][27][28][29][30][31]. Li et al [27] researched precast beam-to-column joint subjected to bidirectional lateral loading to assess precast RC frames under the action of an earthquake.…”

I wish to submit an original paper for publication in Bulletin of Earthquake Engineering, titled "Seismic performance of prefabricated beam-to-column joint with replaceable energy-dissipating steel hinge." The paper was coauthored by Xiao-Yang Chen, Chang-Gui Wei, and Gui-Yun Yan.This study presents a novel prefabricated beam-to-column joint for frame and hysteretic tests was conduct to evaluates the seismic performance and the restorable functional characteristics of the proposed joints. We believe that our study makes a significant contribution to the literature because the proposed prefabricated joint providing advantages for precast concrete reinforced frames, such as complete assembly, damage control, and maintainability of the structure after an earthquake.
