Investigation of Low-Ductility Geogrid Reinforcement for Ground-supported Concrete Structures

Steel rebars are the dominant reinforcement elements in reinforced concrete structures due to their relatively adequate manufacturing, material property and established construction codes. In an ideal environment and under nominal loading, conventional concrete reinforcement is expected to govern the design strength based on which they are designed. However, under environmental loading conditions, such as very low or very high temperature, deterioration of the steel reinforcement is accelerated and lead to significant structural, economic and environmental losses. In Canada, especially the north, steel reinforcement deteriorates due to the above mentioned reasons and an alternative is motivated. Recently, geogrid material is proposed to replace conventional reinforcement for various structural and nonstructural elements. While the latter possess undesirable effects on concrete structure behavior, new geogrid material, ConForce Grid, poses solutions to the common geogrid problems and has the potential to act as adequate reinforcement for structures prone to abnormal environmental conditions. The research work aims at understanding ConForce Grid under standard and environmentally influenced conditions. The research work also aims at creating useful results for the proposed structural elements.
