MPC New Approaches to Strengthen Deteriorated Concrete Bridges
Posted: Jun 16, 2020
MPC research at the University of Colorado Denver will improve the understanding of embedded carbon fiber reinforced polymer (CFRP) systems for concrete bridge members, and will enhance the durability of strengthened concrete members and provide new techniques for bridge engineers who want to adopt state-of-the-art repair techniques to strengthen bridges and extend their lifespans.
The researchers explored the feasibility of a novel anchor system that mitigates the end-peeling of CFRP sheets used for strengthening reinforced concrete beams. Contrary to conventional anchoring methods, CFRP sheets are embedded inside the pre-grooved concrete and covered by a durable polyester-silica composite. Fourteen strengthened beams were loaded in flexure to assess the performance of the proposed anchor system.
