Project Title: Evaluation of CFRP Composites in Rehabilitation of RC Structures

Sponsored by: United States Army Construction Engineering Research Laboratories

Research Objectives:

• Development of strengthening technique for military dormitory-type buildings located in high seismic zones of the United States.
• Investigate the effects of application of carbon fiber reinforced polymer (CFRP) sheets on the stiffness, structural performance, ductility, and mode of failure of the beam, column and beam-column joint.
• Development of non-linear finite element model.

Accomplishments To Date:

• A significant number of CFRP wrapped and un-wrapped beams, columns and beam-column joints were tested for cyclic loading.
• Analysis on the experimental data.

On-going Work:

• Fabrication, casting and testing of more beam, column and beam-column joints.
• Specimens subjected to various environmental conditions.
• Specimens subjected to fatigue loading.
• Development of non-linear finite element model.
