This paper’s objective is to provide simple design relations for the reinforced concrete slabs by a hybrid reinforcing of uniaxial or triaxial geogrids in addition steel rebars. We hope this can guidance further researchers estimate flexural bending capacity slabs, necessary grade geogrids, and count geogrids’ layers conducting first-principles analytical, quantitative analyses previously publi...

large size direct shear tests (i.e.300 x 300mm) were conducted to investigate the interaction between clay reinforced with geogrids embedded in thin layers of sand. test results for the clay, sand, clay-sand, clay-geogrid, sandgeogrid and clay-sand-geogrid are discussed. thin layers of sand including 4, 6, 8, 10, 12 and 14mm were used to increase the interaction between the clay and the geogrid...

Geogrids are commonly used in transportation applications for stabilization and reinforcement due to their higher tensile strengths compared to geotextiles as well as the stiffness improvement they provide through arresting and interlocking granular particles in the geogrid apertures. Influenced by many factors, such as the aperture shape and size of geogrid, the degree of interlocking contribu...

Abstract The objective of this study is to investigate a hybrid reinforcement method for concrete beams, which consists steel rebars and HDPE (high-density polyethylene) uniaxial geogrids, by developing an experimental comparative investigation between utilizing different grades layers geogrids as the primary or extra rebars. experiments included 24 reinforced beams in order provide rich data f...

By installing FBG sensors on the geogrids, smart geogrids can both reinforce and monitor the stability for geogrid-reinforced slopes. In this paper, a geogrid-reinforced sand slope model test is conducted in the laboratory and fiber Bragg grating (FBG) sensing technology is used to measure the strain distribution of the geogrid. Based on the model test, the performance of the reinforced soil sl...

Waste tires have excellent mechanical performance and have been used as reinforcing material in geotechnical engineering; however, their interface properties are poorly understood. To further our knowledge, this paper examines the pull-out characteristics of waste tire strips in a compacted sand, together with uniaxial and biaxial geogrids also tested under the same conditions. The analysis of ...

Geosynthetics have been used in many construction and environmental projects recent years, the use of geosynthetic products as an effective element is increasing. These materials, reinforcement, can solve problems building heavy structures roads on weak soils without need for excavation or filling, foundation, sub-foundation operations. In this study, using different number type materials with ...

Plastic materials are widely used in geotechnical engineering, especially as geosynthetics. The use of plastic-based products involves serious environmental risks caused by their degradation. Innovative research has been focusing on biodegradable polymers natural origin, poly(lactic acid) (PLA), to reduce the plastics. This study aims explore potentiality biopolymers for production geogrids, me...

Geotextile is one of the reinforcement materials adopted in many engineering structures. Conventional geotextiles have a limited effect due to insufficient friction strength between and soils. This paper proposes novel type geotextile with stitched transverse ribs improve effect. A series large-scale direct shear tests been conducted, improvement characteristics conventional geotextiles, geogri...
