Analysis of Composite Fiber Reinforced Concrete Slabs
Authors: Scott Tomlinson and Levon Minnetyan P.E., Member ASCE
Presenter: Scott Tomlinson
Principal Investigator: Levon Minnetyan
Objective
• Investigate the Design of Reinforced Concrete Slabs Without Steel– Use Fiberglass Base– Increase Slab Life Span– Increase Slab Strength
• Use CODSTRAN Computer Simulation– Avoid Curing Time for Concrete– Make Changes Easy to Enact
Methods
• Validate Computer Modeling Technique
• Extend Model to the Desired Design– Multiplex
• Include Variations In:– Loading - Concentrated Vs. Distributed– Fiber Depth
• Expand Fiber Reinforcements Widthwise

Tests
Next Steps
• Finish Evaluating Variations in Fiber Depth
• Expand Width Again– Run Distributed Loads– Run Concentrated Loads– Vary Fiber Depth on each
• Estimated Computer Time, 6 more days
