“…Peng et al [23] and Ma et al [24] found that the existing formulas cannot predict the peak load and failure modes of squat RACSWs and proposed a mixed flexural and diagonal compression mechanism. The dynamic responses and failure modes of ordinary concrete and RAC specimens were compared and discussed by using the shaking table test on RAC frame-shear walls [25].…”

Experiments were performed on four specimens of steel frames with infilled recycled aggregate concrete shear walls (SFIRACSWs), one specimen of infilled ordinary concrete wall, and one pure-steel frame were conducted under horizontal low cyclic loading. The influence of the composite forms of steel frames and RACSWs (namely, infilled cast-in-place and infilled prefabricated) on the failure modes, transfer mechanisms of lateral force, bearing capacity, and ductility of SFIRACSWs is discussed, and the concrete type and connecting stiffness of beam–column joints (BCJs) are also considered. Test results showed that infilled RACSWs can increase the bearing capacity and lateral stiffness of SFIRACSWs. The connecting stiffness of BCJs slightly influences the seismic behavior of SFIRACSWs. In the infilled cast-in-place RACSWs, the wall cracks mainly extended along the diagonal direction. The bearing capacity was 2.4 times higher than in the pure steel frame, the initial stiffness was 4.3 times higher, and the displacement ductility factors were 2.44–2.69 times higher. In the infilled prefabricated RACSWs, the wall cracks mainly extended along the connection between the embedded T-shape connectors and walls before finally connecting along the horizontal direction. Moreover, shear failure occurred in the specimens. The bearing capacity was 1.44 times higher than that of the pure steel frame, the initial stiffness was 2.8 times higher, and the displacement ductility factors were 3.32–3.40 times higher. The degradation coefficients of the bearing capacity were more than 0.85, indicating that the specimens demonstrated a high safety reserve.

“…Most of the studies concentrated on material characteristics of RCA, and mechanical and durability characteristics of recycled aggregate concrete (RAC) [1][2][3][4][5][6][7][8][9]. While there is significant number of studies about safely utilization of RCA in new concrete applications in the literature [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], there is a lack of experimental and analytical study on the structural performance of structural members incorporating RAC, particularly on seismic performance of these members. In order to fulfill this gap, a comprehensive experimental study, in which the full-scale structural members such as reinforced concrete (RC) slabs and columns were tested for investigating the effect of inclusion of low-quality (sourced from low strength concrete) RCA on bending, flexure and shear performances of these structural members, was conducted.…”

In connection with rapid urbanization and earthquakes, a huge number of structures have been demolished and generated lots of waste concrete for the last 40 years. Studies on the reclamation of the waste concrete is a pioneer subject for construction sectors in the world. Since the recycling of the waste concrete and reusing of recycled concrete aggregate in the production of new concrete is an important issue for saving of natural resources, economic, sustainable development, significant number of studies have been carried out on this subject. In the scope of this study, a literature review is conducted on the effect of recycled concrete aggregate on mechanical and durability characteristics of small-scale members. Furthermore, structural and seismic performances of full-scale reinforced concrete structural members produced with recycled concrete aggregate are discussed. The test results indicated that the structural members containing recycled aggregate exhibited similar structural performance with their counterparts containing natural aggregates. It was also observed that recycled concrete aggregate did not seem to have an adverse effect on seismic characteristics of the structural members such as ductility.

This paper presents an experimental study on the seismic behavior of frame structures made with recycled aggregate concrete (RAC). Three 1:2 scaled frame specimens were tested under lateral cyclic loads and constant vertical load. One of these frames was conventional concrete frame, while the remaining two frames were RAC frames with a recycled coarse aggregate (RCA) replacement percentage of 25 and 50%, respectively. The structural performances, in terms of the failure pattern and mechanism, ultimate lateral load capacity, hysteretic response, backbone curve, ductility capacity, energy dissipation capacity and stiffness degradation were analyzed in detail. The effect of RCA replacement percentage on the seismic performance of RAC frames was investigated carefully. The experimental results indicate that the seismic performance of RAC frame is similar to that of conventional concrete frame and not significantly affected by the incorporation of RCA. All of the tested frames behaved with the same failure pattern, which is a ductile failure mechanism. The average value of the ductility coefficient and the equivalent viscous damping ratio of the RAC frame are 3.55 and 0.089, respectively. The RAC frame structure with an RCA replacement percentage of 50% still has adequate capabilities of ultimate strength, deformation and energy dissipation and is able to withstand an earthquake attack.
