“…To investigate the shear performance of BSP beams, four-point bending shear tests were conducted by Li et al [24] on six BSP beams and one RC beam without retrofitting, as shown in Figures 1 and 2. The shear and tensile reinforcement ratios of all specimens were 1.0% and 2.2%, which guaranteed the shear failure mode occurred first.…”

“…The bolted side-plating (BSP) technique, i.e., anchoring steel plates to the side faces of RC beams using bolts, is one of the steel jacketing techniques and can increase the flexural capacity of RC beams without evident ductility reduction, due to the increase of both compressive and tensile reinforcement [4,23]. Moreover, it can also increase the shear strength and stiffness of RC beams, because the steel plates bolted onto the side faces are in the same plane as the shear force [24,25].…”

Reinforced concrete (RC) beams may need to be strengthened because of material deterioration, structure aging, change of building function, defective design, and the decrease of structural reliability caused by accidental disasters such as earthquake and fire. Thus, the retrofitting of RC beams has become a crucial problem, especially for the old buildings constructed before 1980 in mainland China. A variety of studies have proven that the bolted side-plating (BSP) method is feasible and effective for rehabilitating RC beams in existing buildings and infrastructures. The aim of this paper is mainly to review the previous studies conducted by the authors on the shear performance of reinforced concrete (RC) beams retrofitted using the BSP technique, including experimental, theoretical, and numerical studies.

“…External steel jacket anchored by bolts [3][4][5][6][7][8] was proved to be an effective way to enhance flexural strength and ductility of concrete members. However, the bolted steel plates were prone to fail in local buckling and thus cannot be introduced to the strengthening of masonry walls [9].…”

Masonry structures without effective reinforcement are vulnerable to seismic excitation. An innovative strengthening technique was proposed for damaged and undamaged masonry walls. Six confined masonry units with two aspect ratios were tested under in-plane lateral cyclic loading, which consisted of two control walls, two original walls strengthened with reactive powder concrete (RPC-1), and two damaged walls repaired with RPC (RPC-2). The results of the specimens retrofitted with RPC demonstrated that the proposed technique significantly enhanced the seismic performance of masonry walls in terms of lateral strength, ductility, and energy dissipation. Furthermore, the two repaired specimens had a better distributed cracking pattern than the two strengthened specimens. The analysis of the results leads to a better understanding of the effect and mechanism of RPC seismic retrofitting for confined masonry walls.

“…Wang [13,14] used precambered steel plates to strengthen the preloaded rectangular RC columns. Li et al [15][16][17][18][19] experimentally and numerically studied the feasibility of using bolted side-plated technique to enhance the shear capacity of RC beams. But the studies on nacre inspired structures at macro-scale have yet to be insufficient.…”

Inspired by the nacre’s hierarchically assembled structure, the authors tried to use ultra-high ductile cementitious composites (UHDCC) and stack approach to fabricate structure possessing high flexural ductility and load bearing capacity. A series of beams with specially design was constructed, i.e., monolithically cast beams, monolithically stacked beams and hierarchically stacked beams. Four-point bending tests were carried out to explore the effect of hierarchical assembly on load bearing capacity, flexural deformation and flexural toughness. The test results have indicated that the monolithically stacked beams outperform the monolithically cast beams in both deformability and loading bearing capacity, indicating the effectiveness of stack-based construction. Moreover, the setup of connect/separation between layers further improves the flexural ductility of the hierarchically stacked beams, as compared with the monolithically stacked beams. Digital Image Correlation (DIC) observations indicate that the nacreous-like structure of the hierarchically stacked beam helps to trigger crack deflecting and branching between layers and inside matrix, lead to limited slide between layers, thus effectively relieving concentrated strain inside matrix, postponing the emergence of the critical crack and consequently improving the flexural ductility of nacreous-like UHDCC beams.
