Electrical Resistance and Seismic Behavior of Carbon Nanofiber RC Bridge Columns
Civil infrastructures are generally a country's most expensive investment, and concrete is the most widely used material in the construction of civil infrastructures. During a structure's service life, concrete ages and deteriorates, leading to substantial loss of structural integrity and potentially resulting in catastrophic disasters such as highway bridge collapses. A solution to prevent such occurrences, is the use of Structural Health Monitoring (SHM) technology for Smart Concrete structures. Smart Concrete is concrete reinforced with Carbon Nanofibers (CNF). CNF concrete has many structural benefits. CNF restricts the growth of micro cracks in addition to yielding higher strength and ductility. Additionally, test results indicate a relationship between electrical resistance and concrete strain. A series of RC columns were built and tested under a reversed cyclic loading using CNF as a SHM device. The SHM device detected and assessed the level of damage in the RC columns, providing a real-time health monitoring system for the structure's overall integrity.
