“…There is no direct consistency in terms of stiffness point of view since the initial stiffness of a test frame is dependent on some parameters such as the quality of the workmanship in the construction of the hollow brick infill wall and plastering of the specimen, which played an important role in the displacement history in early cycles.

“…In the studies conducted by Baran and Tankut (2011a, b), precast concrete panels were bonded on to plastered hollow bricks by means of epoxy material and it was proven experimentally that this technique is very effective in increasing the stiffness, lateral load and energy dissipation capacities of infilled RC frames whereas improving their seismic behaviour. Panels were also used by Kahn and Hanson (1979), Kaldjian and Yuzugullu (1983), Frosch et al (1996), Frosch (1999), Kesner and Billington (2005), Okuyucu (2011), Akin and Sezer (2016), Aksoylu and Sezer (2018), and Aksoylu and Kara (2020) in examining the behaviour of infilled frames. It was shown that the use of panels is an effective and convenient method to improve the frame strength and stiffness while reducing costs and saving of time.…”

The aim of this study is to compare the seismic performances of strengthening techniques applied to reinforced concrete (RC) non-ductile frames tested under the effects of seismic loads. In the experimental part of the study, one-third scale, one-bay, two-storey non-ductile hollow brick infilled RC frames were strengthened with five different techniques and tested under reversed cyclic lateral loads. One being reference, five of the frames were infilled with hollow bricks and plastered on both sides, one was strengthened with plain mortar, one was strengthened with steel fiber reinforced mortar, two were strengthened with precast RC plates. The last frame was strengthened with RC infill wall. Strengthening techniques increased strength and stiffnesses of the frames in the ranges from 57% to 189% and from 186% to 486% respectively. In the numerical analysis part, an existing RC non-ductile building located in Istanbul, strengthened with the techniques, were analyzed using a computer program. Numerical results were evaluated in terms of interstorey drift ratio together with the overall seismic performance of the building.

In recent years, the prefabricated subway station structure (PSSS) has become a hot spot of underground structure research. In this paper, the numerical model of a soil–subway station structure in a slowly inclined liquefiable site at the surface is established by using FLAC3D finite difference software. And the applicability of the PSSS under the gently inclined liquefiable site is investigated through the foundation pore water pressure, lateral movement of liquefied soil, and dynamic response and uplift characteristics of the subway station structure. It is found that under the gently inclined liquefiable site conditions, the PSSS exhibits tilting and floating behaviors and has an anti-liquefaction effect within a certain range of surrounding soil layers. Compared with the same type of cast-in-place subway station structure (CIPSSS), it has better resistance to overturning and uplift, and the structure has less stress. Under the premise of ensuring static waterproofing, the PSSS can be applied to surface inclined liquefiable sites.

“…e connection type not only affects the manufacture and installation process of precast components but also determines the overall structural performance. Great efforts have been made to investigate the mechanical performance of various connection types of precast wall panel structures, such as types of sleeve [1], emulative [5], hybrid [6], bolted [10], grouted [11,15], and friction connection [16,17]. In the previous research, the dry connection presented great advantages for low-rise precast buildings, in terms of quick erection, maintenance, and reuse [18].…”

This paper develops a novel dry connection utilizing high-strength bolts and introduces the corresponding low-rise precast wall panel structure system. To investigate the seismic performance of the structure system with full bolt connections, monotonic loading tests of the connection joint and cyclic lateral loading tests of three full-scaled precast shear walls are both conducted. Based on the test data, axial and shear mechanical models of the connection are given. Meanwhile, experimental results show that the failure mode of the connection is dominated by anchored rebar ductile rupture, and the precast structure system presents a stable energy dissipation capacity and a good seismic ductility. The numerical model of the precast shear wall is then developed and validated by the cyclic loading test. Also a simplified calculation method to predict the lateral strength of the precast shear wall is proposed. According to the calculation results, the distance between the center of the connection and the edge of the shear wall is suggested to be 150 mm, while the wall thickness is recommended to be 120 mm or 150 mm. Finally, a three-story precast wall panel structure is employed to assess the collapse performance of the proposed precast structure system by using the presented numerical model. The results indicate that the proposed structure system with full bolt connections has high stiffness and high seismic resistance against collapse.
