Abstract:

In addition to enhancing soil, geogrids of geosynthetic materials are beneficial for stabilizing and strengthening applications in infrastructure. Biaxial Geogrids (BG) are utilized in the most important experimental study of a Geosynthetic Reinforced Concrete Structure (GRCS) to replace conventional transverse steel reinforcement in structures. Laboratory testing was done on the fill material, geogrid, and foundation soil. A saturated soft foundation layer has supported the concrete structures. During constructing the GRCS in the mud soil, the geogrids' strain values were measured and registered. Based on the test results, the GRCS's construction produced more than fifty percent of the pressure in the geogrids, despite the bulk of the strain being encased in the ground. Internal geogrid confinement thus provides an efficient method for increasing the GRCS's ductility and load carrying ability. Because geogrid has wonderful ductile behavior, it can be utilized as a hybrid reinforcement with a conventional steel bar to enhance building seismic performance, making them more durable and requiring less construction effort. By implementing geo-synthetic reinforced concrete, the models accurately predicted the stress-strain response. An examination of the building expenses concludes that the cost of a typical reinforced concrete structure can reach up to four times that of a GRCS using optimal design.
