“…The structural damage assessment of FRC has not been explored yet. It is very essential to determine the damage index (31)(32)(33)(34)(35)(36)(37)(38) of FRC for different percentage of fibre under different types of static and dynamic load. The investigation results from damage assessment may explore new important direction of research.…”

The Fibre reinforced concrete (FRC) has become popular in construction industry in last few decades. Various natural and artificial fibres are added in concrete to enhance the crack resistance property by developing some bonding between fibre and concrete. FRC is not only performs better than conventional concrete but also the fibre reinforced concrete (FRC) has become popular in construction industry in last few decades. FRC is not only performs better than conventional concrete but also it reduces environmental pollution. Actually in many rural area, people are not concerned about the pollution and hygiene. The unused portion of sugarcane fibre, banana fibre, jute fibre are thrown into pond/ lake. After few days they decompose and rotten, that causes pollution in waterbody and disturb the ecosystem. The fibres can be used as additive in concrete to enhance their overall performance as well as to reduce environmental pollution. In this paper, a state-of-art review has been investigated on FRC and its different benefits. Different fibres such as jute fibre, coconut fibre, polypropylene, basalt, areca leaf, glass, mask, plastic, carbon and steel fibre were incorporated in concrete by several researchers in the past decades that have been highlighted in detail in this paper. The performance has been evaluated in terms of load displacement hysteretic pattern, stiffness, ductility, energy dissipation, crack resistance, durability and workability of FRC. The virtue and limitations of FRC have also been discussed. From the existing literature, it is found that the performance of FRC under dynamic load, Damage assessment, Time dependent assessment of damage, Effect of fibre in high-performance concrete (HPFRC) and Life cycle assessment are found as major literature gap that needs to be fulfilled. A case study on damage assessment of FRC has also been conducted in this paper. From the result it is found that the Carbon fibre reinforced concrete (CFRC), Steel fibre reinforced concrete (SFRC) and Areca leaf sheath fibre reinforced concrete (ALSFRC) are experiencing lesser damage in compared to normal concrete without fibre. Based on the existing literature the future scope and probable direction of research of FRC have also been highlighted.

“…Ductility based damage index [7], empirical mode decomposition and fast Fourier integration [8] introduced and applied in RC frame, where it was determined considering pushover curve before and after the occurrence of the earthquake [9]. In this context, a *Corresponding Author Email: pritamhait15@gmail.com (P. Hait) comprehensive review [10,11] has been published by the authors on local and global damage index (LDI and GDI) of both bridges and building along with their mathematical expressions. In the overview seismic zonal (IS: 1893-2016) based damage assessment [12] had been explained for RC buildings with different structural configurations for reliable damage assessment of structures to make the study robust.…”

“…To estimate DI of the structures like RC, steel and timber, Park-Ang method was the preferred choice till date. Estimation of Park-Ang GDI for Multi-degree freedom system (MDOF) involves tedious calculation and takes huge computational time to obtain reliable results [10,11]. In this research, a relationship between Park-Ang damage index and EDPs has been established and presented to simplify the damage assessment RESEARCH NOTE method.…”

Structural damage can be controlled in performance based seismic design (PBSD) according to the requirement under a certain hazard level. During strong ground motion (GM) such buildings suffer minor to major damages depending on the shaking level of GM. The available damage assessment methods are complex, tedious and time-consuming procedure. In the present study, a simplified empirical model has been proposed that computes the GDI in a single step using the engineering demand parameters (EDPs) namely joint rotation, Inter storey drift (IDR), peak roof displacement. It has been found that the proposed method gives results of GDI near to Park-Ang model. It has been observed that the ground storey suffers maximum damage for all cases. Further, a relationship has been established between ground story DI and global DI. The proposed model effectively estimates reliable DI and could be used as a powerful tool for estimating seismic damage in buildings, especially for massive structures.
