“…BSP is a technique in which the plates are installed to the side faces of the RC beams by means of anchor bolts [41][42][43][44][45][46]. The behavior of this type of beams is determined by the degree of partial interaction at the interface between concrete and steel plates.…”

The mechanical properties of both concrete and steel reinforcement, and the load-bearing capacity of reinforced concrete (RC) structures are well known to be temperature-sensitive, as demonstrated by the severe damage that major fires cause in buildings, followed—in extreme cases—by their collapse. Since in most cases RC structures survive a fire, retrofitting fire-damaged RC members is a hot subject today. In this paper, after a recall on the performance of RC beams and slabs in fire, different repair techniques are considered, among them externally bonded reinforcement, near surface-mounted fiber-reinforced polymers (FRP), bolted side plating, jacketing with high- and ultra-high performance concretes or mortars, and damaged-concrete replacement. Last but not least, the design equations aimed at evaluating the residual load-bearing capacity after repairing are also presented and discussed.

“…Previous researches [27][28][29][30] demonstrated that partial interaction was caused by the slippage between the steel jacket and substrate through the bolt connection, which led to a better strengthening effect. To achieve better collaboration between the masonry substrate and RPC coating, twenty-two 6 mm diameter U-shaped steel bars at a spacing of 250 mm were precast in the mortar joints as shown in Figure 1.…”

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.

“…It has been found (Lo et al, 2014) that 90% of the full strengthening capacity can be achieved when the strain or the curvature factor is chosen to be not less than 0•6. Therefore, for brevity, a unique value (α = 0•6) is chosen for both α ε and α ϕ .…”

“…In light of this situation, a new design procedure is proposed in this paper. First, the design formulas used to compute the flexural strength of conventional RC beams are modified by introducing the recommended optimum strain and curvature factors proposed by the authors (Lo et al, 2014), to take into account the partial interactions in both the longitudinal and transverse directions. Second, design equations are derived for estimating the dimensions of steel plates and the bolt arrangements.…”

Existing reinforced-concrete (RC) beams can be effectively strengthened by anchoring steel plates to the side faces of the beams using bolts, which is known as the bolted side-plating (BSP) technique. Previous studies have found that the performance of BSP beams is primarily controlled by the degree of partial interaction at the steel-RC interface, which can be conveniently quantified by the strain and curvature factors. In this paper, a new simplified flexural design procedure for BSP beams taking into account partial interaction is presented. Some optimum ranges of strain and curvature factors are first introduced to the flexural design of BSP beams. By ensuring the flexural capacity of a 81 Structures and Buildings Volume 169 Issue SB2
