The 2017 Infrastructure Report of America* cites that nearly 40% of the country’s bridges are more than 50 years old. This is only one statistic stating that America’s building infrastructure is aging. Rehabilitation and maintenance of older structures and buildings is becoming more critical every day, which also increases the need for further education around assessment and preservation techniques and solutions.
One viable solution is the use of general-purpose carbon fiber-reinforced polymer (CFRP), however, its use has been limited due to the lack of expertise and familiarity in design with the material. The following featured article, Ensuring Durable Performance of CFRP-strengthened Concrete, specifically focuses on a strengthening application of CFRP, among the many that exist.
