  1. 1. Composites Advantage, LLC<br />Carbon Fiber Composite Solutions for Structural Strengthening & Protection<br />
  2. 2. Specialty engineering firm<br />FRP experts<br />Materials systems supplier<br />Applicator and Architectural Finishes<br />Who is Composites Advantage, LLC ? <br />
  3. 3. FRP is a strengthening tool<br />Conventional strengthening tools<br />Concrete enlargement (shotcrete), underpinning, post tensioning, steel plates<br />Fiber-reinforced polymers (FRP)<br />A composite system (carbon/glass fabric + epoxy matrix) used to augment another composite system (concrete + rebar)<br />Formats: “wrap”, prefab: dowel bars, plates, strips <br />FRP provides on the outside what concrete is missing inside (e.g. hoop steel for columns).<br />
  4. 4. Strengthening applications<br />Change of use…increased live/wheel loads<br />Installation of heavy machinery<br />expansion of existing facilities<br />Construction or design defects<br />Code changes…new design criteria<br />legislature driven<br />Seismic retrofit<br />Blast protection<br />Deterioration remediation<br />For concrete columns, beams, slabs, walls<br />
  5. 5. Fiber composites<br />Fabric can be custom cut at project site<br />Easy to handle and install<br />
  6. 6. Fabric Manufacturing<br />Spools of fibers are combined into fabrics and pre-cured strips<br />
  7. 7. Key FRP concepts<br />Confinement <br />Columns<br />Think of a weightlifter’s waist belt<br />FRP keeps column rebar from buckling<br />Added tensile strength<br />Underside of beams<br />Shear strength<br />Walls<br />Adds in and out-of-plane strength<br />
  8. 8. From military to construction<br />
  9. 9. History of FRP for construction<br />Mid 1980s<br />EU and Japan begin FRP research and development<br />Late 80s, early 90s<br />Funding for US universities begins<br />Leverage technology developed during the Cold War<br />FHWA, CalTrans*, DARPA<br />UCSD, UofM/Rolla, Penn State, Brown University, North Carolina State, University of Arizona<br />
  10. 10. Composites Testing Lab<br />
  11. 11. Typical Applications<br />CFRP Overlays<br />
  12. 12. Hospitals<br />
  13. 13. Parking Structures<br />
  14. 14. Composites are now accepted for <br />retrofit and rehabilitation<br /><ul><li>20 years of history, over 20,000 projects completed worldwide
  15. 15. ICC, LARR, ACI, Caltrans, FHWA, cities, DSA, and OSHPD* have accepted for a variety of projects</li></li></ul><li>COMPOSITE OVERLAYS <br />FOR <br />BLAST RETROFITS<br />
  16. 16. Blast test results<br />Unprotected column severely deformed from C4 blast<br />Column wrapped in carbon fiber holds up in same blast<br />
  17. 17. FRP’s benefits<br />Engineering benefits <br />Very high tensile strength (10-14x steel) but also ductile (complements concrete’s properties)<br />Very corrosion resistant<br />Architectural and construction benefits <br />Easier to apply/install<br />Lightweight, thin, unnoticeable <br />Minimal structure/tenant intrusion & disruption<br />Economic benefits <br />Low installation costs <br />Great, tangible, ROI<br />FRP works.<br />It’s been reviewed, validated, approved, documented and incorporated worldwide.<br />
  18. 18. Building owner benefits<br />Shorter projects<br />Lower cost<br />Safe and effective<br />Much less tenant disruption<br />Industry/Agency/Peer acceptance<br />
  19. 19. Installation expertise<br />Proper usage (structural engineering)<br />Safety & insurance (look for qualified contractors)<br />Installation environment (doing your homework)<br />Demolition<br />Surface preparation <br />Proper installation techniques<br />Keen attention to detail<br />QA/QC (core competence)<br />Samples collection and mgt.<br />Finishing (virtually any finish can be applied)<br />
  20. 20. FRP benefit: ROI<br />Case Study<br />$18.5M D/B Renovation Project: “BEQ-26”<br /><ul><li>San Diego based Navy barracks underwent renovation, including seismic.
  21. 21. Original plan called for shotcrete for strengthening.
  22. 22. Through collaborative efforts, FRP was VE’d in its place
  23. 23. Navy benefits:
  24. 24. 60% less demolition (landfill)
  25. 25. 50% less disruption
  26. 26. no loss of square footage space
  27. 27. Navy saved $500,000 and 9months (roughly a 36 mo prjt)
  28. 28. Project was 1 of 21 nominees for the 2002 Charles Pankow Award for Innovation</li></li></ul><li>Next steps<br />Composites Advantage, LLC. can meet with you or your SE/architect to discuss FRP’s benefits in more detail<br />VE analysis<br />Free consultation<br />Information is available in CD or print form<br />For projects already spec’d or on the street, we are ready to do the work<br />
