“…In this study, two types of concrete beams with different configurations of transverse reinforcements were taken into consideration. These concrete beams were tested under three-point loading [24]. R. Siva Chidambaram and Pankaj Agarwal 2014; their study investigated the feasibility of geogrids as a confinement reinforcement in steel fiber cement concrete.…”

“…Considerable energy dissipation ability is favorable in the case of large earthquakes under which significant energy dissipation is required because a smaller energy dissipation results in a significant dynamic response and hysteretic damping of concrete structures during earthquakes [29]. Energy dissipation was calculated based on the area enclosed by the load-deflection curve [24]. The behavior of the tested slabs under flexure has also been compared in the form of energy dissipation capacity, which was calculated as the area under its load-deflection curves in Figure 7.…”

This paper aims to innovate a hybrid reinforcement system for concrete slabs, consisting of geogrids and steel bars, by conducting an experimental comparative study between using different types, tensile strengths, and layers of geogrids as additional reinforcement to steel bars in comparison to conventional steel-reinforced concrete control slab. These concrete slabs were tested under a four-point loading system until they failed due to bending. As an addition, strain gauges were attached to the concrete slabs bottom reinforcement (geogrids and steel bars) to provide a close examination of geogrids and steel bars as a hybrid reinforcement system. Results show that the innovated hybrid reinforcement system of uniaxial geogrids and steel bars more preferred as concrete slabs reinforcement as it provided more benefits values (including, but not limited to, initial-peak load, steel-yield load, post-peak load, displacement ductility index, and energy absorption capacity) and more efficient utilization (including, but not limited to, higher benefits to cost values and better flexural performance) than the case of using conventional reinforcement of steel bars and the cases of using triaxial geogrids as additional reinforcement to the steel bars; however, triaxial geogrids provide lower deflection values and higher first-crack load values.

“…Use of geogrids category in structural applications gives promising results in terms of strength and durability. In particular, geogrid reinforcements in structural components is a new technology which increases the overall behaviour of structure in terms of improved load carrying capacity and reduced deflection [22], [48], [56], [57], [59], [63], [66], [67]. The conventional steel in reinforced concrete structure is prone to corrosion under severe environmental condition and thereby it affects the life and durability of the structures.…”

“…To achieve good strength fibers like polypropylene and steel are used [57], [63], [67]. The geogrid reinforcement results in high ultimate load-bearing capacity [22], improved energy absorption and reduced slippage [59], shear and bond strength [67], reduced drying shrinkage [46], [48] and reduced degradation rate [63]. Use of geogrid reinforcement in thin concrete layers [22] and in prefabricated structures [57] was also reported.…”

A type of geosynthetic material named geogrid plays a pivotal role in the behaviour of concrete by implementing them as an additional reinforcement. Geogrids have good tensile strength as they are formed by the reticulation of tensile elements with an opening of an ample size which allows interlock with the nearby fill materials. These grids are flexible mesh which is highly effective and enhances the life of the structure. The prime constituents of geogrid are polyester, high-density polyethylene, and polypropylene. More often, in the field of civil engineering,uni-axial, bi-axial and tri-axial geogrids are used. As the cost and duration of construction are nominal, geogrids can be optedfor cost-effective and resilient construction. They are frequently used as reinforcement and for stabilization in structures like retaining walls, pavements, foundations, slopes, and embankments. The geogrids are employed in various construction which results in sustainable development. Thus, this paper discusses diverse studies that have been carried out by using different types of geogrids for various purposes by different research scholars

“…The concrete members with hooked steel fibres showed a better shear enhancing properties under loads. The Beam confined with Geo-grids and steel fibres showed better flexural strength, stiffness degradation, Energy dissipation capacity, displacement ductility and ultimate load with its corresponding deflection [1,2]. The experimental programme with different types of Geo-grids showed the better confinement with enhanced strength in concrete members.…”

Concrete is a heterogeneous mixture. The behaviour of concrete in addition of any relevant materials needs proper investigations. The steel fibres in concrete enhance the shear capacity of concrete members and Biaxial Geo-grids in Concrete enhance the tensile capacity of concrete members. The concrete is very poor in tension as well as in shear but strong in compression. The main aim of the study is to investigate the tensile and flexural behaviour of Biaxial Geo-grid with and without steel fibres and compared with regular conventional specimens. In this study Compression test on cubes, Split tensile test on cylinders and Flexure test on prisms with one point loading were performed with the 0.5%, 1% , 1.5% volume fraction of hooked fibres with Biaxial Geo-grids into consideration. The experimental tests with the Biaxial Geo-grid and 1.5% volume fraction of hooked steel fibres showed significant improvement in all strengthening aspects. Further this study helps to know the possibility of Biaxial Geo-grid and steel fibres as substitute for tensile and shear reinforcement.
