“…where the yielding drift θ y can be determined according to the criteria suggested by farthest point method (Feng et al, 2017a) and the ultimate drift θ u can be determined by the test, at which point the lateral carrying capacity is close to 80% of the maximum value (Zhang and Jia, 2016). The lateral displacements and drift ratios which corresponding the four characteristic points are listed in Table 3.…”

“…To study the energy dissipation capacity of the SRUHSC frame during loading process, the first hysteresis loop at each displacement level is selected, and its area is calculated by numerical integration to get the cumulative energy dissipation curves at different loading displacements. The equivalent viscous damping coefficient h e was first proposed by Jacobson in 1930 (Zhang and Jia, 2016). It has become an important index, which is usually adopted to evaluate the energy dissipation capacity of the structure.…”

“…The mixed displacement-controlled mode was adopted, meaning that three cycles with drift ratio θ = Δ/ H = 0.2%, 0.3% and 0.4% were initially applied, and each cycle repeated once. Subsequently, the loading process repeated three times at each displacement level for the drift ratio θ = 0.6%, 1.0%, 1.4%,…, until the specimen carrying capacity lost to 80% of the peak carrying capacity (Zhang et al, 2016). Displacement-controlled lateral cyclic loading was then applied with the loading history, as shown in Figure 3.…”

“…However, structure damage or collapse of high-rise buildings caused by earthquake always results in serious consequences. Ultra-high-strength concrete (UHSC) is becoming more and more popular around the world due to many advantages over normalstrength concrete (NSC) in high-rise buildings and larger-span bridges (Ellobody and Young, 2011;Nie et al, 2010;Sun et al, 2018aSun et al, , 2018bZhang and Jia, 2016). Moreover, UHSC structural columns are particularly prominent for the possibilities of increased loadcarrying capacities and stiffness.…”

This article provides the results of an experimental study on the seismic behaviour of the steel-reinforced ultra-high-strength concrete frame. A two-bay and three-story one-fourth scale steel-reinforced ultra-high-strength concrete frame specimen was tested under simulated earthquake loading conditions. The seismic behaviours of the specimen, including the failure mode, concrete element cracks development, hysteresis loops, lateral load-carrying capacity, ductility, energy dissipation, strength and stiffness degradation, were investigated under low reversed cyclic lateral loading. The test results showed that the beam hinge failure mechanism of the steel-reinforced ultra-high-strength concrete frame was achieved. The steel-reinforced ultra-high-strength concrete frame would have rich and stable hysteretic loops when subjected to large axial load with an axial load ratio of 0.38. The roof and interstory ductility coefficients of the steel-reinforced ultra-high-strength concrete frame ranged from 5.06 to 6.78. The strength and stiffness degenerated gradually, indicating an excellent seismic behaviour of the steel-reinforced ultra-high-strength concrete frame with sufficient ductility and high energy dissipation capacity. The test and analysis results can be served as a design reference for practical engineering applications.

“…In the concrete design codes of many countries, such as European nations, the United States, and China [10][11][12][13], the concrete strength is almost always limited within the range of C80; thus, a compressive strength value beyond 100 Mpa, which is usually defined by ultrahigh strength concrete, is not code-accessible, which consequently impedes the development of this structural system to some extent. Secondly, existing work has mainly focused on ordinary strength concrete at the component level [14][15][16][17][18], while research on the seismic behavior of SRUHSC frame structures still remains at the theoretical stage [19][20][21]. For the SRUHSC system, the influence of columns on the overall system, as well as the global response of the frame structure, has not been systematically explored.…”

The seismic behaviors of steel reinforced ultrahigh strength concrete (SRUHSC) frames with different axial compression ratios and shear span ratios are experimentally studied through the reversed cyclic loading test of four specimens. The test results reveal that the seismic response of the frame is closely related to the failure process and failure mode of the columns. Based on the results, a systematic exploration is further conducted in terms of the characteristics of the skeleton curve, hysteresis curve, strength degradation, stiffness degradation, and energy dissipation capacity of the structure. The results indicate that as the axial compression ratio increases, and the shear span ratio decreases, the failure process of the entire structure and the weakening of the beam end are accelerated. Meanwhile, a change of the failure mode is also observed, accompanied by corresponding changes in the strength, stiffness, and energy dissipation capacity of the system.

This paper proposed three composite strengthening methods for repairing seismic‐damaged RC frames to restore their seismic capacity. Combined with the damage characteristics and failure mode of the frame under the earthquake action, the local strengthening of the column adopts the angle steel and gusset plate, and then the whole frame is strengthened by the inclined brace, the thin‐walled steel plate and the V‐shaped buckling restrained brace (BRB), respectively. Through the cyclic loading test, the main seismic indexes of the strengthened specimen, including hysteresis curve, skeleton curve, ductility, energy dissipation capacity, and stiffness degradation, are studied. The influence of different strengthening methods on the seismic performance of the seismic‐damaged specimens is analyzed. The results show that the seismic performance of strengthened specimens is significantly improved, and the bearing capacity, ductility, and energy dissipation capacity are increased by 2.58–5.57, 1.05–1.24, and 7.67–15.87 times, respectively. The thin‐walled steel plate shear wall and the inclined brace are destroyed at first during loading to effectively delay the premature destruction of the main frame. The composite strengthening method makes the original frame realize the failure mechanism of “strong joint weak member, strong column weak beam” under strong earthquake action. The strengthened specimen satisfies the seismic requirement and has good seismic performance. The seismic performance of the frame strengthened with the V‐shaped BRB is better than that of the other two strengthening methods. Based on the test date, the formula for calculating the shear‐bearing capacity of the beam end is presented.
