Designing Composite Repairs and Retrofits for Infrastructure

advertisement:

Techniques for designing laminated composites can be utilized for this purpose.

A method of analyzing and designing laminated composite-material wraps for columns, arches, domes, and other large reinforced-concrete structures involves an extension of composite-mechanics concepts and computational techniques developed previously for the analysis and design of the composite materials only. As used thus far, "composite materials" denotes polymeric matrices reinforced with polymeric or nonpolymeric fibers — e.g., epoxy reinforced with glass fibers. Wraps made of composite materials can be applied to reinforced concrete structures to repair them or as retrofits for reinforcement against loads that are expected to exceed original design loads.
