Fiber Reinforced Concrete01:22

Fiber Reinforced Concrete

Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

  • To correlate epoxy properties with specific structural damage levels.

Main Methods:

  • A novel sensing system bonding zigzagged fiber optic cables with specialized epoxy onto steel specimens.
  • Implementing OTDR technology to detect signal modulations caused by epoxy strain and structural deformation.
  • Conducting monotonic and cyclic loading tests on steel specimens instrumented with the fiber optic sensing system.

Main Results:

  • The fiber optic sensing system successfully identified damage states in steel specimens.
  • The system accurately recorded maximum local deformation during loading tests.
  • Damage evolution and progression were effectively monitored and identified.

Conclusions:

  • The developed fiber optic monitoring methodology is effective for seismic damage identification in steel structures.
  • The sensing system provides real-time data on local deformation and damage states.
  • This approach enhances structural health monitoring capabilities for critical infrastructure.
