Fiber-reinforced-polymer (FRP) strengthening is common in rehabilitation and repair construction projects. Products for this type of strengthening come in several different shapes and sizes including sheets, precured shapes, and near-surface-mounted bars. FRP can be used to add shear and flexural strength to structural elements and can also be used to add confinement in existing structural members with significant seismic forces.

Topics covered in this presentation include:

•Strengthening options

•Components and general properties

•System selection

•System design

•Construction

•Maintenance
