“…In this study, 120 reinforced concrete buildings were surveyed using the earthquake disaster risk index method, and it was determined that the risk index of buildings in the Koyna region was severe, necessitating retrofit measures. Also, a study was done by [65] for seismic vulnerability assessment of a 6-storey building built in the year 2010, located in Columbia. The study concluded that the use of steel jacketing can improve the compressive strength and flexural study of the columns.…”

Seismic vulnerability assessment of any building is done to evaluate the expected damage from future earthquakes. The vulnerability assessment is a time-consuming procedure and difficult as well. Rapid visual screening (RVS) method is a quick and efficient process to identify and rank the buildings. This study describes and compares the outcome of previous researches on conventional RVS methods. This paper summarizes the comparative study among various RVS methods used around the world. Methods have been evolved on the basis of prevalent geographical conditions The various methods for RVS have different scoring patterns. The method differs with different parameters such as load path, no. of stories, weak stories, torsion, pounding effects etc. The comparison chart is drawn for the damageability scales of different countries. The limitations and advantages of various RVS methods have also been discussed. The review of the traditional method can help in the derivation of new techniques in the field of vulnerability study using fuzzy logic and artificial intelligence.

“…In a study of the seismic-resistant behavior of a six-story-high building structure that was reinforced with the cover steel column cladding method, it was found that the reinforced structure had higher lateral strength and a higher toughness value. However, it was also found that structural irregularity can reduce a building's seismic resistance [7]. In a study of the seismic-resistant behavior of a three-story building structure that was reinforced by the column cladding method with steel mesh and expanded metal, the results showed that the stiffness value and lateral force resistance value of the reinforced structure were higher.…”

This article presents a study of the use of ferrocement and expanded metal in the columns, beams, and walls of a reinforced concrete building structure to increase its seismic resistance. This study focused on a concrete building with three stories, located in Thailand. In the design of the reinforcement structure, a calculation and analysis of seismic resistance were conducted in a comparison of the original concrete building structure with the reinforced concrete building structure using the nonlinear static force method (pushover analysis method). The results showed that the seismic resistance of the reinforced concrete building structure was higher than the design value (DPT), with different seismic resistance values for the reinforced frames, columns, and walls of approximately 14%, 81%, and 19%. In particular, it had increased stiffness values for the frames, columns, and walls and increased ductility values for the walls. Moreover, the seismic resistance values originating from the reinforcement were significantly higher than those of the concrete building structure. Therefore, reinforcement should be applied to all concrete building structures with the implementation of the damage index, ensuring that it is reduced to the allowable level.

“…Furthermore, the construction sector is on the lookout for lighter, seismic-resistant materials that don't only reduce the overall dead weight of a structure but also absorb vibrations [14]. As a direct consequence, composites are used in a wide range of structural aspects for the rehabilitation or strengthening of pre-existing structures to make them seismic resistant [15]. Composite materials contain two or more physically and/or chemically distinct phases.…”

Bamboo is an ancient structural material used for a variety of applications in India. Bamboo is widely used in the global south for frames, bridges, housing, and transitory structures. Bamboo supply has been effectively inexpensive as well as plentiful in global south countries to meet the widespread need for affordable housing. The current research focuses on the mechanical properties of bamboo fibre reinforced polymer composite materials for use in structural industries. Moreover, a bamboo fibre reinforced composite was compared to glass fibre in a variety of ways, and it was discovered that the bamboo fibre composite outperformed the glass fibre in a few areas. Investigations revealed the potential use of bamboo fibre reinforced composite with good stiffness but a lower strength limitation than glass fibre composite. Tensile strength of 40.53 MPa and hardness value of 68.2 RHN were achieved by E-glass epoxy composites. However, the results of bamboo fibre reinforced composites cannot be overlooked. Further research was conducted to improve the mechanical properties, and the results were satisfactory.
