The fiber-reinforced polymer (FRP) composite materials that have been used for decades in the aerospace industry are now being used to strengthen existing concrete structures. The use of these materials as external reinforcement for concrete structures has become the preferred method of strengthening over more traditional techniques, such as section enlargement, external post-tensioning and steel-plate bonding. Whether used to increase the load-bearing capacity of a structure, or to restore loss of capacity from damage or deterioration, seismic retrofit or blast hardening, the MapeWrap FRP strengthening system offers a simple, cost-effective method to address structural deficiencies.
This presentation will introduce the unique characteristics of FRP materials, the various components of the MapeWrap FRP system, and general design considerations and limitations. Several case studies will be covered, including those focusing on corroded bridges, structurally deficient bridges and general repair of bridges. Attendees will leave with a greater understanding of which materials should be specified for particular applications, the advantages and limitations of FRP versus traditional strengthening techniques, available design guidelines and codes, and engineering assistance that is available from MAPEI Corporation.
- Learn about the types of FRP systems that are available for the strengthening and repair of concrete bridges.
- Gain an understanding of the different types of fibers that are used, as well as the advantages and disadvantages of each type.
- Learn the various applications of bridge strengthening where FRP systems can be used (e.g., flexural, shear, seismic, etc.).
This is a presentation with Roads & Bridges magazine.
