• Innovative reinforcing schemes
• Self-sensing FRP structural health monitoring
  systems

12
Highly Recommended Topics for investigation
(Contd)

• Need for integrated education
• Education in Schools of Engrg. and Arch.
• Training of design professionals
• Need for development and integration of student
  courseware in civil engineering and architecture

13
Highly Recommended Topics for investigation
(Contd)

• Research Partnerships
• Close collaboration between academe and industry
  is essential
• Innovative industry/academe/government
  partnerships must be developed to facilitate
  seminal research
• Interaction between industry and academe should
  take the highest priority and is likely to yield
  the most fruitful results

14
Other Recommended Topics for investigation

• Hybrid Connections
• External FRP Fundamental design philosophies
• Hybrid Innovative design approaches
• Hybrid Mechanical anchorage, bonded or not
• Durability Extrapolate short-term test results
  to service life
• Internal FRP Structural performance issues
• External FRP Emerging systems
• Fire Residual strength of members

15
Other Recommendations

• Synergized testing
• National coordinated program
• Comparison of test standards
