“…Similarly, as a column strengthening material, it also significantly increases ductility and energy dissipation as well as load-bearing capacity and stiffness [62][63][64][65]. However, very limited studies have been carried out on beam-column joint strengthening using ferrocement [66][67][68].…”

Deformation Capacity of RC Beam-Column Joints Strengthened with Ferrocement

Beam-column joints constructed in the pre-seismic building code do not provide transverse reinforcement and good reinforcement detailing within the region. These cause the occurrence of brittle shear failure, which is one of the factors affecting the number of reinforced concrete (RC) moment resistance building structures collapsing during an earthquake. Therefore, in this study a brittle beam-column joint with a non-seismic building code was designed and strengthened by a ferrocement. Four layers of wire mesh with a diameter of 1 mm and a mesh size of 25.4 mm were installed on both sides of the beam-column joint and cement mortar was cast on it. As a comparison, a ductile beam-column joint was also designed following the current building code, which considers seismic effects. The test results by applying reversed cyclic loading at the beam tip showed that strengthening using ferrocement prevents crack propagation, increasing the deformation capacity, ductility, stiffness, and energy dissipation of beam column joint which are higher than those of the beam-column joint which is designed following the current building code. However, the strengthening does not improve the load carrying capacity significantly.

“…Changing the function of concrete structures may need retrofitting and repair of such buildings. Strengthening using advanced composites or fiber-reinforced polymers (FRP) is a promising approach to improve or regain the loadcarrying capacity of structures to extend their serviceability (Shaaban and Seoud, 2018). FRP gained wide acceptance as a promising technique for retrofitting structural members for its high strength-to-weight ratio, its damping capabilities, its high resistance to corrosion, its fatigue resistance, and the short time scale for repair (Panahi et al, 2021).…”

Concrete has gone through significant changes in popularity in the United Kingdom. This paper explores factors associated with shifts in the perception, and reuse of concrete buildings. and how these changes have influenced the use of concrete in Architecture and Design in the UK. The popularity of concrete has fluctuated over the past few decades. This is driven by a combination of cultural, aesthetic and sustainability factors. In the 1980’s and 90’s fairfaced, textured, bush-hammered concrete acquired a reputation which took some three decades to reverse. UK public opinion on concrete ‘Brutalist’ buildings of these decades is mixed, but tends to often be negative, where terms used include ‘Depressing’, ‘Hideous’, ‘Monstrosities’, ‘Eyesores’. There is currently a growing appreciation for the history and cultural significance of concrete and specifically ‘Brutalist’ architecture. Although these buildings were previously despised, they are now recognised as part of the UK’s architectural heritage and efforts are made to preserve them for future generations. Buildings and complexes, which were once run-down urban environments, are now changed into more desirable housing complexes often leading to drastic social changes in the area. Concrete has been generally seen as a material that has significant environmental impact, especially in terms of carbon emissions. Concrete’s durability, thermal mass and fire protection properties paired with advances in technology that can improve the appearance and consistency of finishes, have all improved the popularity of concrete. Strides are also being made to improve the sustainability of concrete constituent materials. The positioning of concrete as a sustainable, energy efficient building material that can also have an aesthetic appeal, combined with its versatility and durability, make concrete once again a popular choice for contemporary architecture and Interior design.

“…A di erent investigation has been conducted both numerically and experimentally to access the e ect of using ferrocement in di erent structures-like columns, columnbeam joints, slabs, channels, and hollow beams to improve the shear performance under di erent types of loading [2][3][4][5][6][7][8]. In those studies, the ferrocement was used by replacing in place of transverse (stirrups) and longitudinal steel reinforcement.…”

This study presents an extensive analytical investigation of the shear performance of reinforced concrete beams by using ferrocement composite as transverse reinforcement. Nonlinear finite element simulation was conducted in Abaqus 6.14 software package. Fifteen beam models were selected under two-point loading. The main parameters considered includes the diameter, spacing, number of layers of wire mesh, and its combination with stirrups. The results testified that as the diameter and number of layers of wire mesh increased, the ultimate failure load, shear capacity, and stiffness of the model specimen also increased. However, as the number of layers becomes greater than three, no significant change happens in the shear performance of the beam. In another way, the failure load, shear capacity, and stiffness of the beam models are decreased, as the spacing between wire mesh is increased. Furthermore, the study confirmed that under the same weight criteria, the shear performance of RC beam specimens with wire mesh and its combination with stirrups as shear reinforcement is greater than specimens with stirrups only. Finally, the sensitivity analysis is conducted in MS excel to access the effect of each independent variable on the ultimate failure load of the RC beam.
